Ripple effects
The paper’s irregularities came to light when Jack Lawrence, a master’s student at the University of London, was reading it for a class assignment and noticed that some phrases were identical to those in other published work. When he contacted researchers who specialize in detecting fraud in scientific publications, the group found other causes for concern, including dozens of patient records that seemed to be duplicates, inconsistencies between the raw data and the information in the paper, patients whose records indicate they died before the study’s start date, and numbers that seemed to be too consistent to have occurred by chance....
Reliable data needed
The paper’s withdrawal is not the first scandal to dog studies of ivermectin and COVID-19. Hill thinks many of the other ivermectin trial papers that he has scanned are likely to be flawed or statistically biased.
Many rely on small sample sizes or were not randomized or well controlled, he says. And in 2020, an observational study of the drug
was withdrawn after scientists raised concerns about it and a few other papers using data by the company Surgisphere that investigated a range of repurposed drugs against COVID-19. “We’ve seen a pattern of people releasing information that’s not reliable,” says Hill. “It’s hard enough to do work on COVID and treatment without people distorting databases.”
