Fig. 5From: Nomogram model for the risk of insulin resistance in obese children and adolescents based on anthropomorphology and lipid derived indicatorsCalibration curve for internal validation of the nomogram model Calibration plot of the nomogram. The diagonal dotted line showed an ideal model for the perfect prediction ability, the red line (Apparent line) represents the reality performance of the nomogram, and the green line (bias-corrected line). The closer fit to the diagonal dotted line, the better prediction ability of the nomogram. Back to article page
