Calibration plots and slopes of the new and existing pneumonia hospitalization prediction models.

<p>The dots represent the observed frequency of pneumonia hospitalization in 10 groups divided by similar predicted probabilities, and a straight line through the dots represents the calibration slope. The bars represent 95% confidence intervals of the proportion of the observed frequency of pneumonia hospitalization in the 10 groups. The black dots and bars indicate our new model, the red indicate Comparative Model 1, and the blue indicate Comparative Model 2.
