The conclusion states:

In conclusion, we can affirm without a doubt, based on test of comparison of proportions and its confidence interval, as well as the paired tests where we used the Wilcoxon – Mann – Whitney test (α: 95%), that the data in most of the variables (P<0.05) obtained indicate that chlorine dioxide is effective in the treatment of COVID-19, making RT-PCR negative in one hundred percent of cases at 7 days, significantly and rapidly modifying the symptoms of the disease, significantly reducing laboratory parameters to normality within 14 to 21 days. We recommend conducting randomized double-blind studies and delving into studies of toxicological safety and therapeutic efficacy of chlorine dioxide in pathologies of epidemiological impact in the near future.
