We used the method described by Pain et al. to calculate the gene expression prediction models for QTL summary data. Briefly, this method calculates ten TWAS prediction models using eight leading summary statistic methods (top1, PRS-CS, SBayesR, SBayesR-robust, DBSLMM, LDpred2, lassosum, and SuSiE). Chromosome positions were based on GRCh37 and SNPIDs were based on dbSNP 155. Cis gene regions (upstream and downstream 1 MB for the gene in eQTL and 500 KB for pQTL) were included.
