Figure 3.

Forest plots of odds ratios (ORs) for four single-nucleotide polymorphisms supported by acute kidney injury (AKI) association testing in the replication population. Odds ratios from each tested population and resulting metaanalysis based on a fixed-effect model are shown with error bars indicating the 95% confidence interval (CI). Heterogeneity variance (τ²) and statistic (I²) were calculated from a random-effects model as described in the online supplement. The P value is reported for Cochran’s Q test. A nonsignificant Q test result suggests that contributing samples are statistically represented by one underlying distribution.
