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
Optic neuritis is an inflammatory demyelinating disease of the optic nerve that often occurs in multiple sclerosis (MS) patients. Sixty percent of patients develop some level of permanent visual loss due to retinal ganglion cell (RGC) damage following optic neuritis, with no known treatment to prevent this loss. Prior studies showed that MP201, a prodrug of 2,4-dinitrophenol (DNP) administered in the experimental autoimmune encephalitis (EAE) mouse model of MS attenuated optic neuritis with preserved vision, increased retinal ganglion cell (RGC) survival, decreased axon loss, and reduced demyelination. Oral administration of MP201, which converts to active form DNP after entry in the portal vein, decreases mitochondrial-derived reactive oxygen species (ROS) and restores calcium homeostasis, which are both implicated in many neurodegenerative diseases. Due to the established therapeutic benefits of prodrug MP201 in EAE mice, we hypothesized that administration of DNP itself may also have significant potential for therapeutic effects. Here, effects of varying doses of DNP treatment in EAE mice were assessed by the extent of spinal cord paralysis, optokinetic response (OKR), RGC survival, and optic nerve demyelination and inflammation. Results show that daily oral doses of 5-10 mg/kg DNP initiated after onset of EAE can significantly reduce spinal cord paralysis, a marker of the EAE MS-like disease, by day 42 after disease induction. DNP treatment significantly reduces RGC loss induced by optic neuritis in EAE mice; however, effects of DNP do not significantly improve visual function, or optic nerve demyelination and inflammation. Current studies show DNP treatment promotes increased RGC survival, but continued inflammation and demyelination likely reduce visual function, suggesting future studies examining combination therapy of DNP with anti-inflammatory agents may be warranted.
