Logistic regression for biomarkers. (A) Range hazard ratios and confidence intervals for OS and baseline proportions of immune biomarkers before therapy with peg-IFNα. Those with P < .05 are marked in red. (B) Range hazard ratios for PFS as for panel A. (C) Summary table including significant range hazard ratios for biomarkers associated with OS and interaction with GVHD. Biomarkers with a nonsignificant P value for GVHD are predictive of outcome independent of GVHD, and those with a significant P value for GVHD display significant interaction with this clinical outcome. (D) Summary table for PFS as for panel C. Generalized logistic regression and Cox proportional hazard analysis were performed with JMP Pro 14.0.0 (SAS Institute).
