Statement of Concern and Request for Retraction: Clinical Infectious Disease’s Acceptance of “Roman et al.”

Statement of Concern and Request for Retraction: Clinical Infectious Disease’s Acceptance of “Roman et al.”

Note that views expressed in this opinion article are the writer’s personal views and not necessarily those of TrialSite.

We have sent an Open Letter to the Editor-in-Chief of the journal “Clinical Infectious Disease” to recommend an investigation and consequent retraction of a highly problematic meta-analysis titled “Ivermectin for the treatment of COVID-19: A systematic review and meta-analysis of randomized controlled trials” Re: Roman Y M, Burela P A, Paspuleti V, Piscoya A, Vidal J E and Hernandez A V (“Roman et al.). There are a number of identified, material concerns associated with this study that merit the imminent escalation to the journal’s leadership.

An “Accepted Manuscript” in Clinical Infectious Diseases, Roman et al. does not meet the standards of accuracy and integrity that any learned journal should demand. In asserting Conclusions that are not defensible on the evidence presented, it makes no contribution to science or medicine. In its present form, it should be retracted.

Unscrupulous Campaign Against Mounting Ivermectin Evidence

The irony in the authors’ point of view cannot be ignored while they declared:

“in the context of a misinformation infodemic, the dissemination of these results caused confusion for patients, clinicians (in particular those without training in critical reading of the scientific literature) and decision-makers, who may manipulate the information with political interests.”

Yet Roman et al is not the first review of the efficacy of Ivermectin in Covid-19. Other systematic reviews and meta-analyses are available in the public domain. The conclusions of this latest review should mirror those of previous reviews when additional trials are added.

Not Acceptable in Respected Journal

With misreporting of source data, highly selective study inclusion, “cherry picking” of data within included studies, and conclusions that do not follow from the evidence, this article amounts to disinformation.

Disinformation should not be associated with any learned journal of repute. Publication of this article as it stands does a grave disservice to Clinical Infectious Diseases and the good name of Oxford University Press.

    1. The author of those posts argument is, “HCQ was bad, so that means IVM must be too.” That’s a little like saying “Attempts at heavier-than-air-flights failed before so that means the Wright brothers must fail to.”

      There are literally dozens of positive reports on ivermectin, and maybe 1 or 2 showing no effect. It is simply unreasonable to suppose they are all showing positive effects by just coincidence:

  1. The authors state that they have no conflicts of interest on the MedRxiv. However, Dr. Paspuleti’s affiliation is Cello Health. From their website ( Cello provides services such as “Brand and portfolio commercial strategy for biotech and pharma”. Their clients are “… 24 of the top 25 pharmaceutical companies …”. That support is the definition of conflict of interest. Dr. Paspuleti needs to disclose exactly who funded his time and effort on this project.
