Fig. 4From: A prognostic nomogram for event-free survival in patients with atrial fibrillation before cardiac resynchronization therapyCalibration curves at different time points. Red lines represent the correlation between actual values and predictive values. Diagonal dashed lines represent the most perfect prediction. The cross signatures represent corrected predictive values versus actual values. a One-year calibration curve. b Two-year calibration curve. c Five-year calibration curve. d One-year calibration curve for the alternative model based on complete casesBack to article page
