Receiver operating characteristic analysis for the prediction of overall survival in patients with gastric cancer. Receiver operating characteristic analysis of the sensitivity and specificity for the prediction of overall survival by the combined miR-34a expression and tumor node metastasis stage model, the tumor node metastasis stage model, and the miR-34a expression model. P values show the area under the receiver operating characteristic curves (area under the curve) of the combined miR-34a expression and tumor node metastasis stage model versus area under the curves of the tumor node metastasis stage model or the miR-34a expression model.
