STAT4 and neoplasm: The analysis revealed that the TT genotype of STAT4 rs7574865 compared with the GG genotype increases the odds of LSCC T1 tumor by three times (OR = 3.019, 95% CI: 1.362–6.693, p = 0.007), and each T allele increases these odds by 1.6-fold according to the additive model (OR = 1.557, 95% CI: 1.116–2.172, p = 0.009) (Table 9).
