Calibration of risk models for (A) current smokers, (B) former smokers, and (C) the combined group of ever smokers. Plots show predicted and observed estimates of 1-year lung cancer incidence in the test set by deciles of predicted risk. Probabilities were calculated for each year each individual was followed. Bars at each decile show the 95% confidence interval for the predicted probability. The observed number of cases and person-years of exposure in the top 3 deciles are shown at the bottom of the figure.
