RETN and lung cancer: Unconditional logistic regression analysis, adjusted for age and sex, revealed no significant association between RETN SNPs and lung cancer risk in the additive (rs1862513: adjusted OR = 0.935, 95% CI = 0.716–1.221, p = 0.623; rs3745367: adjusted OR = 0.977, 95% CI = 0.757–1.261, p = 0.857), dominant (rs1862513: adjusted OR = 1.032, 95% CI = 0.714–1.491, p = 0.868; rs3745367: adjusted OR = 1.127, 95% CI = 0.783–1.621, p = 0.521), and recessive (rs1862513: adjusted OR = 0.726, 95% CI = 0.433–1.218, p = 0.225; rs3745367: adjusted OR = 0.744, 95% CI = 0.460–1.202, p = 0.227) models (Table 1).
