To clarify the impact of multiple (covering the same population,intervention, control, and outcomes) systematic reviews (SRs) on interventions for myocardial infarction (MI). STUDY DESIGN AND SETTING: Clinical Evidence (BMJ Group) sections and related search strategies regarding MI were used to identify multiple SRs published between 1997 and 2007. Multiple SRs were classified as discordant if they featured conflicting results or interpretation of them.RESULTS: Thirty-six SRs (23.5% of 153 on the treatment or prevention of MI) were classified as multiple and grouped in 16 clusters [ie, at least two SRs with the same PICO (population, condition/disease, intervention, control) and at least one common outcome] exploring angioplasty, angiotensin-converting enzyme inhibitors,anticoagulants, antiplatelets, beta-blockers, and stents. Complete agreement on statistically significant differences between interventions was found in 7 of 10 clusters with a shared composite outcome. Agreement was reduced when single outcomes were considered. Despite substantial variation and limited agreement in reporting of major outcomes, SRs agreed in their conclusions on the superiority of either the intervention or control in 14 of 16 clusters. Sources of minor discrepancies were found in terms of study and outcome selection, subgroup analyses, and interpretation of findings. CONCLUSION: Multiple SRs agreed in their qualitative conclusions but not on reporting and on analyses of hard outcomes. Discordance on significance of treatment effects was due to a combination of variation in design with inclusion of different studies and lack of precision for single hard outcomes compared with a composite outcome. Such inconsistencies among SRs could potentially slow the translation of SRs' results to clinical and public health decision making and suggest the need for a broader methodological and clinical agreement on their design

“…However, since the publication of those reviews, additional data have been published, and the discussion about the indications for operative treatment is ongoing 13,18 . Even though the present meta-analysis has substantial overlap with previous ones, we believe that it adds methodological quality and incorporates recently published data to provide the best currently available evidence to support clinical decision-making 19 .…”

AbtractBackground The process of systematically reviewing research evidence is useful for collecting, assessing and summarizing results from multiple studies planned to answer the same clinical question. The term ''systematic'' implies that the process, besides being organized and complete, is transparent and fully reported to allow other independent researchers to replicate the results, and therefore come to the same conclusions. Hundreds of new systematic reviews are indexed every year. The growing number increases the likelihood of finding multiple and discordant results. Objectives To clarify the impact of multiple and discordant systematic reviews, we designed a program aimed at finding out: (a) how often different systematic reviews are done on the same subject; (b) how often different systematic reviews on the same topic give different results or conclusions; (c) which methods or interpretation
