Assessment of model calibration for sFlt-1, PIGF, sFlt-1/PIGF ratio (continuous) and sFlt-1/PIGF cut-off-based models. sFlt-1, PIGF and sFlt-1/PIGF ratio (continuous) values are in log scales. Estimated probabilities are plotted in ten risk groups. The plot for sFlt-1/PIGF cut-off-based model is based on the log odds of predictions of the 0/1 outcome. A = calibration slope, B = c-statistic, CI - confidence interval, Loess - Locally weighted polynomial regression
