Sorry, but did you actually read the study you cited?

Here is a key quote from your citation:

Importantly, close to 70 trials worldwide are currently testing the clinical benefit of ivermectin to treat or prevent SARS-CoV-2 (see Table 3); these include variations on dosing regimens, combination therapies (preliminary results for NCT04523831 in Table 3, #45) [46,47], and prophylactic protocols.

The paper you are citing is saying that at the time 70 trials were underway, not completed. It cannot and does not draw any conclusions about those studies, because they hadn't concluded. And it mentions promising results from exactly one recently completed trial at the time the paper was written.

The links I shared are more relevant and discuss the analysis of the data from the completed trials.
