Receiver-operating characteristics curves and predicted risk versus observed risk of outcomes of a final risk score for predicting MetS and recovery from it.

<p><b>(A)</b> In MetS cohort, the final risk model predicted the recovery from MetS. <b>(B)</b> The final score predicted subsequent MetS in the whole population without MetS at enrollment. <b>(C)</b> Calibration plots for prediction of recovery from MetS in the prevalent MetS population at enrollment were good with an intercept of 0.95, a slope of 0.96, and an R² of 97% (p <0.001). <b>(D)</b> The final score demonstrated good calibration for predicting incident MetS in the whole population with an intercept of 0.69, a slope of 0.95, and an R² of 98% (p <0.001).
