  • Data are means ± SD, unless noted otherwise. Comparison of age between categories was carried out by ANOVA. Pair-wise comparisons were carried out using the least significant difference method. Hazard ratios are estimated using the stratified Cox proportional hazards model (stratified by the study from which the data were derived) and adjusted for age, sex, and ethnic group.
