LPP and lung cancer: These three polymorphisms (rs1064607, rs3796283 and rs2378456) in LPP, which increased the risk of lung cancer among males, were identified using the dominant model (rs1064607, GC-CC vs GG, OR = 1.57, CI = 1.06–2.33, p = 0.024; rs3796283, GA-GG vs AA, OR = 1.67, CI = 1.10–2.51, p = 0.014; and rs2378456, GC-CC vs GG, OR = 1.55, CI = 1.02–2.38, p = 0.041), with power values of 0.799, 0.866, and 0.718, respectively.
