Meta-analysis of miR-499 rs3746444 polymorphism with cancer risk.

SCCHN: squamous cell carcinoma of the head and neck; HB: hospital based; PB: population based; HWE: Hardy-Weinberg equilibrium; OR: odds ratio; CI: confidence interval; P: p value; P-H: P value of Q for heterogeneity test; I2: 0–25%, no heterogeneity; 25–50%, modest heterogeneity; 50%, high heterogeneity; aNumber of studies involved. Random effects model was used when P value of Q for heterogeneity test (P-H)<0.05 or I2>50%; otherwise, fixed effect model was used.
