Chronic oral methylene blue treatment in a rat model of focal cerebral ischemia/reperfusion.
Article in Brain research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
A single acute low-dose methylene blue (MB), an FDA-grandfathered drug, has been shown to ameliorate behavioral deficits and reduces MRI-defined infarct volume in experimental ischemic stroke when administered intravenously or intraperitoneally. The efficacy of chronic MB treatment in ischemic stroke remains unknown. In a randomized, double-blinded and vehicle-controlled design, we investigated the efficacy of chronic oral MB administration in ischemic stroke longitudinally up to 60 days post injury using MRI and behavioral tests, with end-point histology. The major findings were chronic oral MB treatment, compared to vehicle, i) improves functional behavioral outcomes starting on day 7 and up to 60 days, ii) reduces MRI-defined total lesion volumes from day 14 and up to 60 days where some initial abnormal MRI-defined core and perfusion-diffusion mismatch were salvaged, iii) reduces white-matter damage, iv) gray matter and white matter damages are consistent with Nissl stains and Black Gold stain histology. These findings provide further evidence that long-term oral administration of low-dose MB is safe and has positive therapeutic effects in chronic ischemic stroke.
