= number of subjects, (%) = frequency of subjects; odds ratios and 95% CIs were derived from logistic regression models comparing the homozygous wild-type genotype (GG genotype for TIMP-2 -418G/C and 303G/A was taken as reference) with other genotypes. Significant values () and related OR have been shown in bold.
