Univariate Cox regression analysis of molecular characteristics associated with PFS according to ctDNA and tumor biopsy sample sets, in FL and DLBCL cohorts of the baseline biomarker population. References for LymphGen comparisons included patients with a single LymphGen subtype, those with multiple subtypes, and those classified as “other.” For patients with multiple subtypes, if one of those subtypes was the same as the comparator subtype, then that patient was excluded from the reference group (hence the varying N numbers). ABC, activated B cell; ref, reference.
