(A) Association of SNPs at 5p15.33 with lung cancer, adjusted for sex, age, study site, % sub-Saharan African ancestry, % European ancestry, and number of pack-years smoked. Circles denote associations for all lung cancer histologies compared to controls. Squares denote associations for adenocarcinoma cases compared to controls. Triangles denote associations for squamous-cell carcinoma cases compared to controls. Crosses denote associations for squamous cell carcinoma cases compared to controls.
