Figure 2. Forest plot for the association of high versus low 25(OH)D levels in patients with colorectal cancer.
(A) Forest plot for the association of high versus low 25(OH)D levels with overall survival in patients with colorectal cancer. (B) Forest plot for the association of high versus low 25(OH)D levels with CRC-specific survival in patients with colorectal cancer. HR: Hazard ratio; CI: Confidence interval. * Cohort1 studied by Vaughan-Shaw; # Cohort2 studied by Vaughan-Shaw.
