Risk of incident lung cancer according to genetic risk and the TyG index. Participants were divided into categories of low (quintile 1), intermediate (quintiles 2–4), and high (quintile 5) genetic risk strata. The TyG index was defined as low and high according to median level (TyG index = 8.639). The hazard ratios were estimated using Cox regression models after adjusting for age, sex, region, Townsend deprivation score, smoking status, alcohol intake frequency, body mass index, waist hip ratio, and hypertension, fasting time, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and glycated hemoglobin as well as the top 10 principal components of the ancestry and genotyping array. TyG index, triglyceride-glucose index.
