Vitamin D3 supplementation significantly reduces cancer-specific mortality.
Vitamin D3 may help reduce the risk of dying from cancer. This finding is based on a smaller subset of trials than the general mortality benefit, so it should be viewed as a potential secondary benefit rather than the primary reason for supplementation. The reduction is statistically significant but modest.
Vitamin D3 statistically significantly decreased cancer mortality (RR 0.88 (95% CI 0.78 to 0.98); P = 0.02; I2 = 0%; 44,492 participants; 4 trials).
Why this rating
Statistically significant but based on only 4 trials and 44,492 participants; trial sequential analysis did not cross the monitoring boundary for benefit.
