Correlation doesn't equal causation. One of the most basic rules in scientific research. That's why research is important. Solid, peer reviewed research carried out by experts. Not people with Google who think they understand the data.
For example, the largest peer reviewed meta-analysis found the following:
Ivermectin showed no evidence of an effect on increasing or decreasing mortality at 28 days, the most important outcome during this pandemic, neither in inpatients (two studies), outpatients (two studies), or the preventive setting (one study). The certainty for this finding was very low. The same accounts for clinical worsening up to 28 days in an inpatient setting and up to 14 days in an outpatient setting.
With regard to clinical improvement, ivermectin may have little or no effect compared to placebo or standard of care on clinical improvement up to 28 days and duration of hospitalizations in an inpatient setting. For outpatients, ivermectin may have little or no effect on the number of participants with symptoms resolved up to 14 days. Based on very low certainty evidence, there was no significant increase in viral clearance at seven days in participants treated with ivermectin in inpatient settings and based on low‐certainty evidence for outpatient settings. For adverse events, ivermectin may have little or no difference on occurrence of adverse events within 14 days in an outpatient setting, while we are uncertain about the effect of ivermectin on adverse events within 28 days in an inpatient setting.
