Figure 2
Calibration plot for the premenopausal breast cancer model, using observations from three studies [16–18]. The solid line indicates perfect calibration; the dashed line is a regression line (); the dotted line is a least-squares line, weighted by the number of observed breast cancer cases represented by each data point, an approximate measure of sample size ().
