Figure 1 Free T and DHEAS at age 14, by categories of age 14–19 annual reports of menstrual cycles ≥42 days (0, 1, 2, or ≥3). Unadjusted mean ± SD values are displayed. P values (analysis of variance adjusting for race): free T: ≥3 reports .0017 vs. 0, .0069 vs. 1, .0083 vs. 2; DHEAS: ≥3 reports .0054 vs. 0, .050 vs. 1, .0007 vs. 2; 2 vs. 1.038.

Figure 3 Glucose (at ages 10, 19, and 24), insulin (at ages 10–16, 19, and 25), and homeostasis model assessment insulin resistance (HOMA-IR; at ages 10, 19, and 24) by categories of age 14–19 annual reports of menstrual cycles ≥42 days (0, 1, 2, or ≥3). Unadjusted mean ± SD values are displayed.
