ComboBatch: a benchmark of transcriptomic harmonization methods for follicular lymphoma and DLBCL

Code, metric tables and figures accompanying a systematic benchmark of transcriptomic batch-effect harmonization across 7,174 samples from 88 follicular lymphoma, DLBCL and normal B-cell cohorts spanning 19 platforms. 39 harmonization methods were implemented and 31 evaluated across 14 sample-removal strategies, 3 imputation modes and 2 post-removal variants, scored on 87 metrics in 14 groups, yielding a biomaterial- and platform-conditional decision tree for choosing a harmonization method.
