Fig. 3From: Triglyceride-glucose index linked to all-cause mortality in critically ill patients: a cohort of 3026 patientsRestricted cubic spline regression analysis of TyG index with in hospital all-cause mortality. Heavy central lines represent the estimated adjusted hazard ratios, with shaded ribbons denoting 95% confidence intervals. TyG index 9.2 was selected as the reference level represented by the vertical dotted lines. The horizontal dotted lines represent the hazard ratio of 1.0. A Restricted cubic spline for hospital death. B Restricted cubic spline for ICU death. HR hazard ratio, CI confidence interval, TyG triglyceride-glucoseBack to article page
