title: The effect of dyslipidemic drugs on mortality: A meta-analysis.
abstract: Most of the previously published meta-analyses include studies exploring the effect of statins, rather than all dyslipidemic drugs, on mortality. We explored the overall effect of all dyslipidemic drugs on coronary artery disease mortality, cardio-vascular disease mortality and all-cause mortality. A meta-analysis of all randomized controlled trials that were published before February 2006 was carried out. Data sources were published articles in bibliographic electronic databases and medical journals. The article selection criteria included all randomized placebo-controlled trials of at least one year duration and those which measured at least one of the following clinical endpoints: coronary artery disease mortality, cardio-vascular mortality or all-cause mortality. Information on sample size, follow up period, drug used, and clinical outcomes was abstracted independently by two authors. Disagreements were resolved by consensus. The meta-analysis (19 trials, 59033 patients) showed a significant relative risk reduction of coronary artery disease mortality of 23% (P<0.00001), cardiovascular disease mortality of 19% (P<0.00001) and all-cause mortality of 14% (P<0.0001), without any significant heterogeneity and inconsistency between the trials. It was concluded from this meta-analyses that dyslipidemic drugs are indeed highly effective medicines and confer benefit to patients, in terms of primary and secondary prevention of coronary artery disease.
