LN = lymph node, rs = correlation coefficient. Univariate and multivariate analyses of risk factors affecting lymph node metastasis To determine the risk factors predictive of lymph node metastasis, we further examined the correlation of lymph node metastasis with other clinicopathological factors. As shown in Table 3, advanced T-classification was significantly correlated with lymph node metastasis (p = 0.036).
