Figure 5

Metaregression analysis in present meta-analysis investigates association between COX-2 polymorphisms and susceptibility to oral cancer ((a) +837 T > C (rs5275) in allele model; (b) +837 T > C (rs5275) in dominant model; (c) −765 G > C (rs20417) in allele model; (d) −765 G > C (rs20417) in dominant model; (e) 1195 A > G (rs689466) in allele model; (f) 1195 A > G (rs689466) in dominant model).
