Nitazoxanide controls virus viability through its impact on membrane bioenergetics.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Viruses are dependent on cellular energy metabolism for their replication, and the drug nitazoxanide (Alinia) was shown to interfere with both processes. Nitazoxanide is an uncoupler of mitochondrial oxidative phosphorylation (OXPHOS). Our hypothesis was that mitochondrial uncoupling underlies the antiviral effects of nitazoxanide. Tizoxanide (the active metabolite of nitazoxanide), its derivative RM4848 and the uncoupler CCCP were applied to a virus-releasing cell line to obtain the same increasing levels of mitochondrial uncoupling, hence identical impact on OXPHOS. A decrease in infectious viral particle release was observed and reflected the intensity of impact on OXPHOS, irrespective of the nature of the drug. The antiviral effect was significant although the impact on OXPHOS was modest (≤ 25%), and disappeared when a high concentration (25 mM) of glucose was used to enhance glycolytic generation of ATP. Accordingly, the most likely explanation is that moderate interference with mitochondrial OXPHOS induced rearrangement of ATP use and acquisition of infective properties of the viral particles be highly sensitive to this rearrangement. The antiviral effect of nitazoxanide has been supported by clinical trials, and nitazoxanide is considered a safe drug. However, serious adverse effects of the uncoupler dinitrophenol occurred when used to increase significantly metabolic rate with the purpose of weight loss. Taken together, while impairment of mitochondrial bioenergetics is an unwanted drug effect, moderate interference should be considered as a basis for therapeutic efficacy.
