miR-320e (per 0.0052 unitsa) | 38/167 | 1.46 | 1.11–1.91 | 0.0059b | 0.62 |
Tumour location (proximal vs distal) | 1.08 | 0.55–2.11 | 0.8251 | ||
TNM (III vs II) | 2.46 | 1.12–5.37 | 0.0244b |
Abbreviations: CI=confidence interval; CRC=colorectal cancer; DFS=disease-free survival; HR=hazard ratio; OS=overall survival; TNM=tumour, node, metastasis.
This is the IQR, representing an increase from the 25th percentile to the 75th percentile of the miR-320e distribution.
P<0.05.
