Retrospective 16,287 breast cancer and 14,919 prostate cancer showing increased risk of COVID-19 cases with vitamin D deficiency.
risk of case, 35.1% lower, OR 0.65, p = 0.01, high D levels 13,903, low D levels 2,384, adjusted per study, breast cancer patients, logistic regression, RR approximated with OR.
risk of case, 32.4% lower, OR 0.68, p = 0.045, high D levels 13,601, low D levels 1,318, adjusted per study, prostate cancer patients, logistic regression, RR approximated with OR.
