evidence: The authors of this Cochrane systematic review, published today by Cochrane’s Infectious Diseases Group, found no evidence to support the use of ivermectin for treating or preventing COVID-19 infection, but the evidence base is limited. [...] The authors searched for randomized controlled trials that investigated ivermectin to prevent or treat COVID-19 in humans. People being treated with ivermectin had to have laboratory-test confirmed COVID-19 and be receiving treatment in hospital or as outpatients. [...] Main authors of the review, Maria Popp and Stephanie Weibel said: "The lack of good quality evidence on efficacy and safety of ivermectin arises from a study pool that consists mainly of small, insufficiently powered RCTs with overall limited quality regarding study design, conduct, and reporting. Current evidence does not support using ivermectin for treating or preventing of COVID-19 unless they are part of well-designed randomized trials."
