Pharmacology made easy 4.0 the neurological system part 1 quizlet. This sample size provided a level of significance at 5% with 80% power for 2-sided tests. In this randomized clinical trial of early ivermectin treatment for adults with mild to moderate COVID-19 and comorbidities, we found no evidence that ivermectin was efficacious in reducing the risk of severe disease.
