Table 2 Model Performance for arterial stiffness progression

From: Use of lipid parameters to identify apparently healthy men at high risk of arterial stiffness progression

Models AUC (95% CI) NRI(95% CI) p value IDI (95% CI) p value
Outcome 1: Increase in/persistently high baPWV
Age + MAP 0.73 (0.70–0.77)
Age + MAP + LogTG 0.74 (0.71–0.78) 22.9% (7.8–37.9%) 0.003 1.1% (0.4–1.9%) 0.004
Age + MAP + LogTG/HDL-C 0.74 (0.71–0.78) 22.2% (7.0–37.4%) 0.004 1.2% (0.4–2.0%) 0.003
Outcome 2: Incident elevated baPWV
Age + MAP 0.74 (0.69–0.79)
Age + MAP + LogTG 0.75 (0.70–0.81) 40.7% (18.8–62.6%)  < 0.001 1.4% (0.1–2.6%) 0.03
Age + MAP + LogTG/HDL-C 0.75 (0.70–0.80) 32.1% (10.1–54.1%) 0.004 1.1% (0.0–2.2%) 0.06
