A Randomized Pilot Study Using Calcitriol in Hospitalized Patients
RCT 50 hospitalized patients in the USA, 25 treated with calcitriol, showing significantly improved oxygenation with treatment. Mortality, intubation, ICU admission, and hospitalization time also favored treatment, while not reaching statistical significance with the very small sample size.
Elamir et al., 9/8/2021, Randomized Controlled Trial, USA, North America, peer-reviewed, 9 authors, dosage calcitriol 0.5μg days 1-14.
risk of death, 85.7% lower, RR 0.14, p = 0.23, treatment 0 of 25 (0.0%), control 3 of 25 (12.0%), continuity correction due to zero event (with reciprocal of the contrasting arm).
risk of mechanical ventilation, 80.0% lower, RR 0.20, p = 0.48, treatment 0 of 25 (0.0%), control 2 of 25 (8.0%), continuity correction due to zero event (with reciprocal of the contrasting arm).
risk of ICU admission, 37.5% lower, RR 0.62, p = 0.33, treatment 5 of 25 (20.0%), control 8 of 25 (32.0%).
hospitalization time, 40.5% lower, relative time 0.60, p = 0.14, treatment 25, control 25.
relative Δ SaO2/FiO2, RR 0.14, p = 0.03, treatment 25, control 25.
Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
