Late evening and overnight LH characteristics in nonobese (open squares) and obese (solid circles) peripubertal girls by breast Tanner stage. Data are presented as mean ± SEM. The numbers of subjects are below the Tanner stage labels: NO = nonobese, OB = obese. The last column shows obese Tanner 5 girls only with PCOS (solid triangles) and without PCOS (open triangles). Due to blood volume constraints, time point 1900–2300 (subject awake) is used as a surrogate for daytime hormone levels. (McCartney et al, 2009,35 with permission from The Endocrine Society.)
