Note: Mean and standard deviations of continuous variables and counts and frequencies of categorical variables are presented. Cohen's d was calculated for continuous variables and Cramer's V was calculated for categorical variables as estimates for effect sizes. HRS was treated as a survey (N = 1847 with weight associated with enrolling in biomarker substudy, representing a total of N = 27938256 participants).
