Interaction analysis and stratification analysis of BMI trajectories and the PRS constructed by four GWIA-identified SNPs on NSCLC risk. A, BwPRSGWIA were weighted according to the strength of their association with lung cancer. C, DsPRSGWIA were calculated by simple counting. P value for interaction was derived from multivariate-adjusted Cox proportional hazards regression model. PRS, polygenic risk score; GWIA, genome wide interaction analysis; SNP, single nucleotide polymorphism; HR, hazard ratio; CI, confidence interval
