Analysis of 868 patients on renal replacement therapy. Statistically significant reduction in mortality with HCQ for patients on dialysis (OR 0.47,
p=0.005).
No statistically significant change was found for transplant patients (the result is not given but likely the sample size is too small - the number of transplant patients was half the number of dialysis patients).
Sánchez-Álvarez et al., 4/27/2020, retrospective, database analysis, Spain, Europe, peer-reviewed, mean age 67.0, 10 authors.
risk of death, 45.9% lower, RR 0.54, p = 0.005, treatment 322, control 53, odds ratio converted to relative risk.
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.
