We did a systematic review to identify relevant literature, by searching multiple databases using a defined strategy, and by hand searching relevant journals. Evidence of efficacy was determined from randomized controlled trials (RCTs). Evidence of harm was determined from trials or registries where data was gathered prospectively. Ten RCTs with a total of 3,025 participants were included in the efficacy analysis; 28 prospective trials with a total of 3,983 participants were identified and eligible for the review of harm. One unpublished, randomized, unblinded study of 2,103 dialysis patients was designed to measure overall survival and cardiovascular mortality.

Un ECR comportant une période de suivi de 12 mois, auprès de 239 patients atteints de GAO léger à modéré, a évalué l’innocuité et l’efficacité du iStent. L’étude a comparé les patients subissant une chirurgie de la cataracte jumelée à la pose d’un iStent à des patients subissant seulement une chirurgie.

A 12-month follow-up RCT3 involving 239 patients with mild to moderate OAG assessed the safety and efficacy of the iStent. The study compared patients receiving cataract surgery in combination with the iStent versus patients receiving cataract surgery alone. The authors reported that the patients who had the iStent implant experienced statistically and clinically significant benefits in reducing IOP with less medication. The safety profile for the two patient groups was similarly favourable. Follow-up at two years found significantly better IOP control in the iStent treatment group compared with the control group in patients not taking any medication for OAG.

L’essai clinique majeur RELY, randomisé et comparatif (ECR), qui oppose le dabigatran et la warfarine, constate que le dabigatran à la dose de 110 mg comporte moins de risque d’hémorragie grave que la warfarine à une dose adaptée, ce qui ne serait pas le cas du dabigatran à la dose de 150 mg.

Bleeding is typically the main safety issue of concern with all anticoagulants, including dabigatran. In RE-LY, the major randomized controlled trial (RCT) comparing dabigatran with warfarin, the risk of severe bleeding was reduced with the lower 110-mg dose of dabigatran compared with adjusted-dose warfarin, but there was no such reduction with the higher, 150-mg dose. However, there was evidence that in elderly patients there was no reduction in severe bleeding risk at either dose versus warfarin, and in the post-marketing period there was some evidence from case reports that elderly patients and/or those with severe renal impairment are at risk for serious bleeding events.

Un ECR à centre unique, sans insu, comportant une période de suivi de 12 mois, a comparé l’efficacité du TMC au TMC jumelé au PG ou à la gastrectomie longitudinale mis en œuvre dans le but d’améliorer la maîtrise glycémique chez 150 patients obèses atteints de diabète de type 2.

A 12-month follow-up, single-centred, non-blinded RCT compared the effectiveness of SMT with SMT plus GB or sleeve gastrectomy as a means of improving glycemic control in 150 obese patients with type 2 diabetes mellitus. The authors reported that at 12-months, glycated hemoglobin levels of 6% were achieved in 12% of the SMT group versus 42% in the GB group, and 37% in the sleeve gastrectomy group. With the continued use of drugs to lower glucose, lipid and blood pressure levels decreased significantly in the BS groups but increased in patients receiving SMT alone.2

Clinical studies (RCTs and observational studies) examining the optimal duration of clopidogrel therapy suggest that patients with stent placement benefit from the longer-term use of clopidogrel compared with short-term treatment. Studies indicated that the shorter time required for a reimbursement decision in a Canadian provincial drug reimbursement program for clopidogrel therapy is associated with better patient outcomes. One observational study20 implied the possibility of a clopidogrel rebound effect. The authors were unable to identify any study that could help answer the third (plus fourth and fifth), sixth, and thirteenth research question. Few studies examine the effectiveness of dipyridamole or ASA extended-release dipyridamole.

Un ECR comportant un suivi de 12 mois chez 33 patients atteints de GAO ou d’hypertension oculaire a évalué les changements dans la dynamique de l’humeur aqueuse ainsi que l’efficacité et l’innocuité du iStent.

A 12-month follow-up RCT6 of 33 patients with OAG or ocular hypertension evaluated the changes in aqueous humour dynamics, and the efficacy and safety of the iStent. The study population consisted of patients who received two iStents in combination with cataract surgery and patients who underwent cataract surgery alone. At one year, the authors indicated that the iStent group (n = 17) showed a clinically significant increase in trabecular outflow facility, significant IOP reduction, and a reduction in reliance on ocular medications compared with the control group (n = 16).

Un ECR à double insu a comparé l’efficacité de diminution de la PIO procurée par la phacoémulsification seule ou jumelée au iStent, chez 36 patients5. Les résultats ont montré que les patients traités en conjonction avec le iStent présentait une PIO significativement plus basse et une diminution significative de l’usage d’hypotensifs oculaires; 67 % des patients ne faisaient pas appel aux médicaments 15 mois après l’opération, par rapport au groupe témoin.

A double-blinded RCT compared the IOP-lowering efficacy of phacoemulsification alone and in combination with the iStent in 36 patients.5 Results showed that the iStent-treated patients experienced significantly lower IOP and a significant reduction in the use of ocular hypotensive drugs, with 67% of patients being medication free 15-months post-operatively compared with the control group. No adverse events were reported in the study group.

An industry-sponsored, multinational RCT involving 479 patients with above-the-knee femoropopliteal PAD compared the Zilver PTX with balloon angioplasty.2 The primary safety end point was met, with an event-free survival rate at 12 months of 90.5% for patients in the Zilver PTX treatment group and 83.9% for patients in the angioplasty control group. Primary patency rate at 12 months was 82.7% in the Zilver PTX group and 32.7% in the angioplasty group.

Seulement un 10 des 30 ECR est mené auprès d’adolescents (âgés de 10 à 18 ans). Dans les études dont la population est adulte, la durée de la maladie au moment de l’étude va de 711 à 2212 ans (moyenne pondérée de 15,6 et écart-type [ET] de 4,8).

Of the 30 included RCTs, only one10 was conducted in adolescents (aged 10 to 18 years). Baseline duration of illness for the adult studies ranged from 711 to 2212 years (weighted mean [SD] 15.6 [4.8]). A broad range of antipsychotic doses were used in the included trials. Common outcome measures included schizophrenia symptom scales (e.g., Positive and Negative Symptoms Scale [PANSS], Brief Psychiatric Rating Scale [BPRS] scores, Clinical Global Impression [CGI]), response rate, cognition, withdrawals, and serious adverse events. No evidence was available for relapse or remission rates.

En effet, il est établi que les résultats statistiquement significatifs seront présentés, alors que ceux sans importance statistique ne le seront probablement pas34. Comme ce n’est pas la totalité des ECR qui se prêtent à toutes les analyses, la puissance de celles-ci s’en trouve réduite.

This review has limitations. Not all trial reports documented data on all of the outcomes of interest. This may introduce bias, because statistically significant results are more likely to be reported than non-statistically significant results.34 Not all RCTs could be included in the analyses for all outcomes, resulting in reduced power. A handful of clinical trials were used in quantitative data analysis, and the event rates that were reported for some clinical outcomes (such as stroke, major bleeds, and some adverse events) were low. The related computational issues may limit the analyses, and the results are interpreted with caution.

Nasal sumatriptan requires consideration in adolescents. The evidence of effectiveness in adolescents was derived from eight RCTS comparing five triptans to identical placebos. Only sumatriptan 20 mg nasal spray significantly increased the likelihood of a two-hour response, with the combined results of two trials suggesting a number needed-to-treat of 10 (95% CI: 6, 36).The combined response of sumatriptan recipients from both trials showed a 38% response rate for achieving freedom from pain at two hours, with a number needed-to treatof 10 (95% CI: 6, 30]

Sixteen publications3-18 reported findings from 14 randomized controlled trials (RCTs) with a total of 11,317 patients. Based on the meta-analyses performed, no clinically important differences between interventions were found in vascular death, urgent target vessel revascularization, non-fatal MI, stroke, or major bleeds. The only difference that was observed occurred in the comparison of ASA plus ticlopidine to ASA alone for the outcome measure of all target vessel revascularizations. A meta-analysis of composite end point data was considered to be inappropriate, but a narrative review of findings from large RCTs suggests that the use of ASA plus clopidogrel reduced the rates of cardiovascular events compared with ASA alone.
