Multivariate Cox regression analyses of TTT were performed by including the following covariates: CD49d, CD38, ZAP-70, β2M, sCD23, and mod-Rai (206 patients). For each variable, the selected cutoff points or the compared categories are indicated.
TTT indicates time to treatment; RA, hazard ratio; CI, confidence interval; other abbreviations are as in Tables 1 and 2.
Based on the final model after stepwise selection of covariates.
