¹Least squares means and adjusted percents are adjusted for race (white vs. non-white) due to the inclusion of all non-whites in the control group (see methods section for details).

²p values are adjusted for race using linear regression to calculate least squaresd means, adjusted percents and p-values (see methods section for details).

³Intervention arm participants were randomized to finasteride.
