The Spin


Right narrative

A real-world study of 197 cancer patients taking ivermectin and mebendazole found an 84.4% clinical benefit ratio, with nearly half reporting tumor regression or no evidence of disease at six months. The regimen was well-tolerated, affordable and grounded in extensive preclinical evidence showing multi-target anticancer mechanisms. Randomized trials are urgently needed to confirm what this prospective cohort already signals.

Left narrative

This ivermectin-cancer study is an anonymous self-reported survey with no control group, no imaging to confirm outcomes and a 38% dropout rate, conducted entirely by authors who financially benefit from selling the drugs studied. Every outcome measure is unverifiable, and patients were simultaneously receiving chemotherapy, radiation and surgery. The 84.4% "clinical benefit" figure is statistically meaningless given these fatal design flaws.
