Ovarian Cancer and Body Size: Individual Participant Meta-Analysis Including 25,157 Women with Ovarian Cancer from 47 Epidemiological Studies
Figure 4
Relative risk of ovarian cancer by body mass index.
Relative risk in (A) never-users of hormone therapy (HT) and (B) ever-users of hormone therapy, taking women with a body mass index of <25 kg/m2 in each group as the baseline (relative risk = 1.0), and stratified by study, age at diagnosis, parity, height, and duration of oral contraceptive use. Results for never-users of hormone therapy are additionally stratified by menopausal status/hysterectomy, and results for ever-users of hormone therapy are restricted to postmenopausal women. Relative risk estimates are plotted against the mean body mass index in each category (<25, 25–29, and 30+ kg/m2). Case–control studies with hospital controls are excluded.
