According to univariate analysis, miR-939, SLC34A2 level, and TNM stage were significantly associated with OS and time to recurrence (TTR) in patients with GC (Table 2), while multivariate analysis confirmed miR-939, SLC34A2 level, and TNM stage as independent prognostic indicators for both OS and TTR (Table 2). Here, TTR is linked to gastric cancer.
