A Protective Role of Coenzyme Q10 in Ethambutol-Induced Retinal Ganglion Cell Toxicity: A Randomised Controlled Trial in Mice.

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
Ethambutol is a widely used drug to treat tuberculosis that may cause visual disturbance including ethambutol toxic optic neuropathy (ETON). The disease disrupts bodily tissues' energy production, including the retinal ganglion cells (RGC). Many have proposed treatment with coenzyme Q10 (coQ10) due to its antioxidant and facilitative effects that can improve mitochondrial electron transport. The present study hence assessed whether coQ10 could protect against ETON through a parallel triple-blinded randomised controlled trial in 18 mice using computer-generated tables for treatment allocation. All of the mice received 25 mg/kg ethambutol daily, while only nine in the treated group also received 100 mg/kg coQ10. After 30 days, blinded pathologists counted RGC numbers in enucleated and dyed orbital tissue. The treated group had significantly denser RGCs at 47.2 (standard deviation [SD] 10.6) cells per 500 µm microscope field vs 33.5 (SD 6.3) in the control group (t = 3.34, p = .004). CoQ10 therefore protected RGCs from ETON. Clinical trials of coQ10 in human subjects treated with ethambutol should be considered.
