NOTE: When carrying out same multivariate logistic regression, but by using LnGDF-15 as a continuous variable instead of categorized GDF-15 into high (upper tertile) and low (lower 2 tertiles) GDF-15, GDF-15 remained predictive for lymph node metastasis (adjusted OR of 2.3; 95% CI, 1.4–3.9; P = 0.001).
