Multivariate Analysis for Progression

Model 1: Disease Status (n=88)	HR	95% CI	P
ETP	0.98	0.6–1.7	0.9
CR2+	1.6	0.8–3.3	0.2
PIF/CR1	2.9	1.1–7.5	0.03
No CR	3.5	1.5–7.9	0.003
Model 2: MRD Status (n=64)	HR	95% CI	P
ETP	0.7	0.3–1.6	0.4
MRD Positive	2.8	1.3–5.9	0.006

CR status and MRD status were highly correlated variables, so each variable was evaluated independently on multivariate analysis. 88 patients had known T-ALL subtype data, and were considered in model 1. 64 patients had known MRD data by flow cytometry after 2004, when flow cytometry assessment prior to transplant became routine.
