Mean Serum HGF Concentration by Genotype of rs3735520 and Results of Nonparametric Tests under Genotypic, Dominant (CC vs. TC + TT), and Recessive (CC + TC vs. TT) Models

Genotype	n	Mean Serum HGF ± SE	Mean Rank by Genotype*	Mean Rank Dominant†	Mean Rank Recessive‡
CC	31	486.8 ± 39.0	33.35	33.35	37.66
TC	35	527.5 ± 28.7	41.36
TT	12	632.0 ± 68.4	53.08	44.29	53.08

The mean rank of the serum HGF measurements is given by genotype group, as input for the nonparametric statistical tests.

^*Kruskal-Wallis test P = 0.036.

^†Mann-Whitney U test P = 0.039.

^‡Mann-Whitney U test P = 0.032.
