Comparison between C-statistic indices of nested multivariate models predicting ischemic stroke: The PRIME Study^a

Abbreviations: hs-CRP = high sensitivity C-reactive protein; IP-10 = interferon-γ-inducible protein-10; RANTES = regulated on activation normal T-cell expressed and secreted; RF = risk factors.

^aC-statistic indices were derived from unconditional logistic regression models adjusted for matched variables (age, study center, and baseline examination date).

^bThe traditional RF model includes smoking and hypertension as additional covariates; IP-10, RANTES, hs-CRP, and fibrinogen values were log-transformed. c-Statistic indices were compared using the Delong test.
