Table 5 The ORs of  hOGG1  Ser326Cys polymorphisms according smoker status

From: An association between hOGG1Ser326Cys polymorphism and the risk of bladder cancer in non-smokers: a meta-analysis

Allele and genotype Populations OR  I   2 (%)  P  heterogeneity Analysis model  P 
326Cys allele versus 326Ser allele (additive model) a Smoker subjects 1.29 (0.97-1.71) 0% 0.64 Fixed 0.08
Non-smoker subjects 1.59 (1.08, 2.32) 0% 0.65 Fixed 0.02
Cys/Cys versus Ser/Ser (homozygote contrast) a Smoker subjects 1.46 (0.84, 2.56) 0% 0.66 Fixed 0.18
Non-smoker subjects 2.93 (1.43, 5.99) 37% 0.21 Fixed 0.003
Cys/Cys versus Cys/Ser + Ser/Ser (recessive genetic model) a Smoker subjects 1.54 (1.00, 2.37) 0% 0.44 Fixed 0.05
Non-smoker subjects 2.41 (1.47, 3.95) 0% 0.42 Fixed 0.0005
Cys/Cys + Cys/Ser versus Ser/Ser (dominant genetic model) a Smoker subjects 0.72 (0.26, 2.02) 87% 0.004 Random 0.53
Non-smoker subjects 1.58 (0.72, 3.50) 75% 0.02 Random 0.26
