Data are means (SD), except where stated otherwise. Means were compared using paired t-tests for baseline vs follow-up, and t-tests for men vs women at baseline. Proportions were compared using McNemar's test for baseline vs follow-up and a chi-squared test for men vs women at baseline. N/A = not available; a p < 0.05 for baseline vs follow-up (separately in men and women); b p < 0.001 for women vs. men at baseline; c p < 0.001 for baseline vs follow-up (separately in men and women)
