Schematic showing 237 biopsy samples were screened, of which 84 were renal transplant biopsies. Of the remaining 153 native renal biopsies, a further 52 were excluded because DNA was unavailable or because sampling was inadequate for diagnosis at the time of biopsy, or biopsy was not ultimately performed. Following review, another 51 samples were excluded. Ultimately, 50 samples underwent sequencing.
