Figure 1. — Calibration belts for the separate models predicting PICU mortality in the Pediatric Acute Respiratory Distress syndrome Incidence and Epidemiology Version 1 (V1) cohort. The calibration belt examines the relationship between estimated probabilities and observed mortality rates, with associated 80% (light gray) and 95% (dark gray) CIs. Perfect calibration lies along the center (dashed) line. The calibration belt is paired to a statistic that tested deviation from the center line, similar to the Hosmer-Lemeshow test. All four models developed in the V1 cohort demonstrate good calibration (as indicated by p > 0.05 in all models).
