Notes: athe genotyping was successful in 1,003 (98.50%) NSCLC cases, and 901 (99.33%) controls for BTLA rs1982809 G>A. bAdjusted for age, sex, smoking status, alcohol consumption, and BMI (besides stratified factors accordingly) in a logistic regression model. Abbreviations: BMI: body mass index; NSCLC: non-small-cell lung cancer.
