Adjusted hazard ratios (95% confidence intervals (CIs)) for incident circulatory disease associated with number of pregnancies and pregnancy losses. Analyses are stratified by age at risk and study area and adjusted for level of attained education, household income, smoking status, alcohol use, systolic blood pressure, history of hypertension, physical activity, body mass index, and history of diabetes. Analyses for pregnancy loss are additionally adjusted for number of live births. The hazard ratios are plotted on a floating absolute scale. Each square has an area inversely proportional to the standard error of the log risk. Vertical lines indicate the corresponding 95% CIs. Analyses for pregnancy loss are among women with at least one pregnancy
