Cross-cohort meta-analysis for the 10-year risk of incident atrial fibrillation in the FHS (Framingham Heart Study) and the Atherosclerosis Risk in Communities (ARIC) Study cohorts. Hazard ratios (95% Confidence Intervals) are shown for each cohort. Results are adjusted for age, sex and race (in ARIC) and multivariable-adjusted as per text. The I-squared presents the heterogeneity index for meta-analysis across the two cohorts.
