Outcome analysis after the data quality (DQ) application for data retrieved from the FIL-MCL0208 clinical study. Progression-free survival (PFS) curves calculated (A) at the beginning of the study (No_DQ timepoint, n = 277), and (B) after the last milestone (PM-4 time point, n = 300) for the three classes of Mantle Cell Lymphoma International Prognostic Index (MIPI). The log-rank test results are reported in terms of the P values obtained comparing the curves of adjacent classes: low (L-MIPI) versus intermediate classes (I-MIPI; P < .001), I-MIPI versus high classes (H-MIPI; P = .626) for A; L-MIPI versus I-MIPI (P < .001), I-MIPI versus H-MIPI (P = .113) for B. PFS discrimination was based on the infiltration of disease detected by flow cytometry from (C) the No_DQ time point (n = 120) to (D) the PM-4 time point (n = 252). The log-rank test results are reported in terms of P values obtained comparing the curves of adjacent classes: < median versus ≥ median (P < .567) for C (median = 4.45%); < median versus ≥ median (P < .012) for D (median = 6.55%). Significance level set at .05.
