I went to the trouble of figuring the percentages of people in the groups who went to the hospital:
Placebo 1: 14.9%
Placebo 2: 14.0%
Ivermectin: 12.7%
Fluvoxamine: 10.4%
Obviously Fluvoxamine produced the best results. There are various criteria that statisticians use to determine what is a significant difference and apparently by those criteria Fluvoxamine passed and Ivermectin did not.
But I think in general they need bigger sample sizes to be sure. So it's a good thing they are testing both again with a much bigger sample. With a sample of 700 it is hard to say if 13% is statistically different from 14% or just random noise. With a sample ten times that size you will have enough statistical power to make that determination.
