Figure 6 Funnel plots showing the associations between the xeroderma pigmentosum group D polymorphisms and esophageal cancer susceptibility. Each point represents a separate study for the indicated association. A: Funnel plot of XPD Asp312Asn for the dominant model (Asn/Asn+Asp/Asn vs Asp/Asp); B: Funnel plot of XPD Lys751Gln for the recessive model (Gln/Gln vs Lys/Gln+Lys/Lys).
