Background and aims Meta-analyses of randomized control trials investigating the association between incident diabetes and statin use showed an increased risk of new-onset diabetes (NOD) from 9% to 13% associated with statins.

Abstract
Background and aims Meta-analyses of randomized control trials investigating the association between incident diabetes and statin use showed an increased risk of new-onset diabetes (NOD) from 9% to 13% associated with statins. However, short follow-up period, unpowered sample size, and lack of pre-specified diagnostic criteria for diabetes detection could be responsible of an underestimation of this risk. We conducted a meta-analysis of published observational studies to evaluate the association between statins use and risk of NOD. Methods and results PubMed, EMBASE and MEDLINE databases were searched from inception to June 30, 2016 for cohort and caseâcontrol studies with risk of NOD in users vs nonusers, on â¥1000 subjects followed-up for â¥1 year. Two review authors assessed study eligibility and risk of bias and undertook data extraction independently. Pooled estimates were calculated by a random-effects model and between-study heterogeneity was tested and measured by I2index. Furthermore, stratified analyses and the evaluation of publication bias were performed. Finally, the meta-analysis included 20 studies, 18 cohort and 2 caseâcontrol studies. Overall, NOD risk was higher in statin users than nonusers (RR 1.44; 95% CI 1.31â1.58). High between-study heterogeneity (I2 = 97%) was found. Estimates for all single statins showed a class effect, from rosuvastatin (RR 1.61; 1.30â1.98) to simvastatin (RR 1.38; 1.19â1.61).
