Forest plots of the association between MRI-determined silent brain infarction and future stroke in all included studies15–27. Meta-analysis calculated using a random-effects mode, with crude relative risks pooled in panel A and adjusted-hazard ratios pooled in panel B. Squares represent point estimates for the effect sizes. The size of the squares is proportional to the inverse of the variance of the estimate. Diamond represents the pooled estimate and the horizontal lines represent the 95% confidence interval.
