  1. #1 CCRCC clear cell RCC, CRCC chromophobic RCC, PRCC papillary RCC
  2. #2 a,b: Post Hoc Scheffé Test of multiple comparison of each two pair of RCC subtypes for all metrics showed that the MK and Ka values of CRCC were significantly higher than those of CCRCC and PRCC with P values < 0.001 (P < 0.017 was considered significant with Bonferroni correction)
