Abstract: The summary RR for all-cause mortality was (95% CI , ) across all trials.

Results, All-cause mortality: RRs for all-cause mortality could be obtained for 13 trials, representing 66,447 person-years of follow-up during which deaths were recorded. … The summary RR for all-cause mortality in people randomised to metformin compared with all comparators was (95% CI , ). The summary RR for all-cause mortality was 0.91 (95% CI 0.70, 1.18) in trials comparing metformin to placebo/usual care and (95% CI , ) in trials comparing metformin to active comparators (Fig. 3).
