KIF11 and neoplasm: Furthermore, patients whose PAC co-expressed KIF11 and KIF14 at high level had significantly shorter survival time compared to those patients whose tumor tissue simultaneously expressed both these markers at low level (1059 days vs. 334 days; p < 0.0001, log-rank test; Figure S3A), and the combined expression of two markers was only slightly more valuable for predicting prognosis than each marker individually (univariate Cox analysis: HR = 3.41, 95% CI 2.12–5.47; p < 0.0001; Table S2).
