Web1 day ago · To partition and quantify potential sources of single-tissue PZM burden, we fit linear models relating technical and biological metadata to single-tissue PZM burdens and selected the best fitting model identified from detailed model comparisons . The final model contained 12 covariates and explained 48% of the variation in mutation burden.
