Does serum α-Tocopherol have a Nonlinear Inverse Association with Periodontitis among US Adults?
A nonlinear inverse association was observed between serum αT and severity of periodontitis, which was restricted to adults with normal but relatively low αT status. These findings warrant further confirmation in longitudinal or intervention studies.
Expression of VEGF is a predictor of distant metastasis, OS, and DMFS in resectable ESCC patients. Using a combination of VEGF expression, tumor stages, and tumor cell grade, identification of patients with increased risk of postoperative metastases may become possible.
