Table 2. Distribution of IL-6 –174 G/C (SNP rs1800795) genotypes in relation to the total number of subjects and gender. The results are expressed as a percentage (%) in relation to the total sample size of each group.

IL-6 genotypes	Total (%) [N=125]	Male (%) [N=76]	Female (%) [N=49]	p
GG	59 (47.2)	38 (50)	21 (42.9)
GC	52 (41.6)	29 (38.2)	23 (46.9)	0.569
CC	14 (11.2)	9 (11.8)	5 (10.2)

The p value was calculated with the Mann-Whitney U test using SPSS (Statistical Package for the Social Sciences), version 17.0.
