Figure 4

Plots of the observed against the predicted CRQ dyspnea (range from 1 (worst) to 7 (best)) at 12 months. The gray diagonal line represents perfect calibration. The black solid line and red dashed lines are the regression lines for uncalibrated and re-calibrated models. Black open triangular points and red filled square points are based on deciles of predicted CRQ dyspnea from the uncalibrated and re-calibrated models respectively. The dotted gray lines represent the +/-0.5 minimal clinically important difference. The raw data is represented by the gray points. The numbers indicate deciles to which they belong.
