Novel Insights into the Predictors of Obstructive Sleep Apnea Syndrome in Patients with Chronic Coronary Syndrome: Development of a Predicting Model

Figure 3

Calibration curves for the predictive efficacy of the risk nomogram for moderate to severe OSAS in patients with CCS. The y-axis represents the actual probability of patients with moderate to severe OSAS as validated by the sleep monitoring study, and the x-axis represents the predicted risk of moderate to severe OSAS by the risk nomogram. The diagonal dotted line represents a perfect prediction by an ideal model, while the solid line represents the performance of the risk nomogram. A closer fit of the solid line to the diagonal dotted line represents a better prediction.
