  • *The meta-analysis was based on a fixed-effects model.

  • †HR was adjusted for age, gender, smoking status, tumor stage, performance status and treatment.

  • ‡Data for rs2855983 and rs10975179 were not shown owing to their strong linkage with rs1964986 and rs7854413 (r2 >0.8), respectively. In the validation phase, data for rs1964986, rs3782736, rs1573618, rs10108662, rs243538, and rs4789182 were replaced by linked SNPs (r2 >0.8) rs10273639, rs10849524, rs6464489, rs7820268, rs243519, and rs9944529, respectively.

  • ADD, additive; DOM, dominant; P het, p test for heterogeneity; REC, recessive.
