Retrospective study of calcitriol supplementation with chronic kidney disease patients in Catalonia showing lower cases, severe cases, and mortality with supplementation. A dose-response relationship was found for severe cases and mortality.
risk of death, 43.0% lower, HR 0.57, p = 0.001, treatment 2,296, control 3,407, multivariate, patients with CKD stages 4-5.
risk of severe case, 43.0% lower, HR 0.57, p < 0.001, treatment 2,296, control 3,407, multivariate, patients with CKD stages 4-5.
risk of case, 22.0% lower, HR 0.78, p = 0.01, treatment 163 of 2,296 (7.1%), control 326 of 3,407 (9.6%), NNT 40, multivariate, patients with CKD stages 4-5.
