Analysis of Mexico City's use of an ivermectin-based medical kit, showing significantly lower hospitalization with use. Authors use logistic-regression models with matched observations, including adjustments for age, sex, COVID severity, and comorbidities.This preprint was censored by the original preprint host. Censors claim that the government treatment program, which used approved medications and saved over 500 people from hospitalization, was unethical. In part they also indicate that studies of "the effects of a medication on a disease outcome" are outside the scope of their site, however retroactively censoring a paper for this reason is not appropriate.The author's response (not provided by the censors) can be found here: [twitter.com].Author's provide the data and code for the study, and the results have been independently verified.
