Days to negative in the three trial arms:
Ivermictine: avg= 6.0 95% CI= (4.61–7.38)
Control: avg= 9.15 95% CI= (5.68–12.62)
there was only 20 patient in the control group this would give a margin of error of 21.91% for that 95% confidence interval.
Most statisticians agree that the minimum sample size to get any kind of meaningful result in this case would be ~385
