XPD Lys751Gln polymorphism and esophageal cancer risk: A meta-analysis involving 2288 cases and 4096 controls

Figure 1 Odds ratio of esophageal cancer associated with xeroderma pigmentosum group D Lys751Gln polymorphism for the CC genotype compared with the AA genotype. XPD: Xeroderma pigmentosum group D; OR: Odds ratio.

Figure 2 Odds ratio of esophageal cancer associated with xeroderma pigmentosum group D Lys751Gln polymorphism for the CC genotype compared with the AA/AC genotypes. XPD: Xeroderma pigmentosum group D; OR: Odds ratio.

Figure 3 Funnel plot analysis to detect publication bias. Each point represents a separate study for the indicated association. The Odds ration is plotted on a logarithmic scale against the precision (the reciprocal of the SE).
