Figure 9. Begg’s funnel plot for publication bias testing in analyses involving association of rs1805087 with PCa risk. (a: G allele vs. A allele; b: genotype GA vs. AA; c: GG vs. AA; d: GG+GA vs. AA). Each point represents a separate study on the indicated association. Log [OR] stands for the natural logarithm of OR. The horizontal line indicates mean effect size. b: Egger’s publication bias plot of rs1805087 and PCa risk (e: G allele vs. A allele; f: genotype GA vs. AA; g: GG vs. AA; h: GG+GA vs. AA).
