From: Association between two CHRNA3 variants and susceptibility of lung cancer: a meta-analysis
Forest plots of the association between each mutant allele and susceptibility of lung cancer.
For each SNP, the mutant allele could decrease (rs578776 and rs938682) the risk of lung cancer without high heterogeneity (Fig. 2A, OR: 0.83, 95% CI: 0.79–0.86, I2 = 0.0% for rs578776; Fig. 2C, OR: 0.80, 95% CI: 0.72–0.88, I2 = 47.9% for rs938682). Funnel plot for publication bias of two SNPs (rs578776, rs938682). Figure 2B,D showed all researches seemed no obvious asymmetry and had no significant publication bias. P values of Egger’s test for these two SNP were 0.334 and 0.167 respectively.
