Screening key genes predicting lymph node metastasis. A DEGs between lymph node-positive patients and lymph node-negative patients. B The curve of the coefficient path of 32 lymph node metastasis-related genes identified by the LASSO regression in the training cohort. C The selection of the adjustment penalty parameter λ in the LASSO model via tenfold cross validation according to the error within one standard error range of the minimum. D Multivariate logistic regression for 18 genes to identify the key genes that can independently predict lymph node metastasis. OR: odd ratios; LCI: lower confidence interval; UCI: upper confidence interval
