Begg's funnel plot for the superoxide dismutase 2 (SOD2) C47T polymorphism and noise induced hearing loss (NIHL). Allele model, T vs. C (A); co-dominant model, TT vs. CC (B); CT vs. CC (C); recessive model, TT vs. CC + CT (D); dominant model, CC vs. TT + TC (E). logor, odds ratio logarithm; s.e., standard error.
