Kaplan-Meier survival plots for 1-year TRM in relation to Reg3α serum concentrations at the time of ASCT. Kaplan-Meier survival plots show a significant difference between patients with high and those with low Reg3α serum values according to a threshold of 110 ng/mL in both the test (n = 371, P < .001) (A) and validation cohorts (n = 216, P = .009) (B).
