Actually I'd go further and stop citing these XXXmeta.org websites that pop like mushrooms after the rain. It's probably the result of a Python script that pops graphs and tables according to a csv with data from the studies selected.

They do very crude, naive, ad-hoc and cherry picked study selection, and metastudies is one of the most complex and difficult areas to do research on.

On the topic of ivermectin, it certainly displays positive outcomes... in countries with high helminth prevalence. So yeah, treating co-morbidities is certainly better than not treating them, not exactly shocking.
