Figure 2From: N-acetyltransferase 2 (NAT2) gene polymorphisms in colon and lung cancer patients Meta-analysis (Mantel-Haenszel, fixed effects) on 13 case-control association studies on NAT2 slow acetylator status and lung cancer – Caucasians. Test for heterogeneity χ2 (df 12) = 9.02 (p = 0.7012). The summary odds ratio (OR = 1.05, 95% CI, (0.96–1.15) is not significant.Back to article page
