FIGURE 4.
Forest plot of allele comparison of DVWA rs7639618 for overall comparison (A versus G, association of rs7639618 and knee OA). SNP rs7639618 is associated with a significantly increased risk of knee OA in allelic comparison in Asian (A versus G: OR: 1.16, 95% CI 1.04–1.30), and in all allelic models (A versus G: OR: 1.28, 95% CI 1.13–1.46), but not in Caucasians (A versus G: OR: 1.00, 95% CI 0.87–1.16).
