HOTAIR and metastatic malignant neoplasm in the lymph nodes: The comparison showed that patients with at least one minor allele (TC and CC) of rs920778 exhibited a significantly (p = 0.031) lower 0.51-fold risk (95% CI, 0.28–0.94) of developing lymph node metastasis compared to their corresponding WT homozygotes (Table 4), while no associations were found in HOTAIR rs1899663, rs4759314 and rs12427129 with clinicopathologic characteristics in UCC patients (Table A2).
