Figure 4From: Stromal expression of miR-21 in T3-4a colorectal cancer is an independent predictor of early tumor relapseForest plot of meta-analysis for the association of high miR-21 expression and overall survival in colorectal cancer patients. High miR-21 expression is associated with poor overall survival in colon cancer patients but not in rectal cancer. CI, confidence interval; CC, colon cancer; RC, rectal cancer; CRC, colorectal cancer; OS, overall survival.Back to article page
