Figure 1.

Odds ratio (and their corresponding 95% confidence intervals (CIs)) for endometrial cancer by serum levels of SHBG and sex steroids (in tertiles) among postmenopausal women. Solid squares represent odds ratios (ORs), estimated by conditional logistic regression, for tertiles of serum hormone concentrations (cut points based on the distribution of control subjects) and horizontal lines represent 95% CIs. Analysis based on 192 case patients and 374 control subjects. Case patients and control subjects were matched on EPIC (European Prospective Investigation into Cancer and Nutrition) recruitment center, age at blood donation, time of day at blood donation, and fasting status. DHEAS, dehydroepiandrosterone sulfate. ¹P_trend=P value for a test of linear trend across categories based on median hormone values for the three tertiles. ²P_trend=P value for a test of linear trend based on log-transformed continuous variable.
