Model improvement for MAGGIC risk score in combination with SHR

Models	AUC (95% CI)	p value	cNRI (95% CI)	p value	IDI (95% CI)	p value
Model 1	0.60 (0.55–0.66)	< 0.001	Reference		Reference
Model 2	0.65 (0.59–0.70)	< 0.001	0.41 (0.22–0.60)	0.027	0.04 (0.02–0.06)	0.044

Model 1 = MAGGIC risk score; Model 2 = MAGGIC risk score + SHR

AUC: area under curve; IDI: integrated discrimination improvement; cNRI: continuous net reclassification index; CI: confidence interval; MAGGIC risk score: meta-analysis global group in chronic heart failure; SHR: stress hyperglycemia ratio
