Comparing patients with May-adjusted 25OHD levels in the highest versus the lowest tertile, the fully adjusted HR (including adjustment for CRP) was 0.66 (95% CI 0.49 to 0.89) for CRC-specific mortality and 0.65 (95% CI 0.51 to 0.81) (table 3) for all-cause mortality, indicating that postoperative 25OHD influences survival outcome after a diagnosis of CRC independent of sample time point and the inflammatory response. Here, CRP is linked to colorectal carcinoma.
