Quantification of Methylene Blue and Evaluation of Its Pharmacokinetics in ICR Mice by Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry Using Difluoroacetic Acid.

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
Methylene blue (MB), a phenothiazine derivative, is currently under clinical trials for Alzheimer's disease (AD) due to its potential to inhibit tau aggregation, a key pathological process in AD. In this study, we developed and qualified a rapid and reliable liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-qTOF-MS) method for the quantification of MB in mouse plasma and brain samples. Chromatographic separation was achieved using a PolymerX RP-1 100 Å (50 × 2 mm, 5 μm) column with a mobile phase consisting of water and methanol containing 0.5% difluoroacetic acid, delivered at a flow rate of 0.5 mL/min. Calibration curves were constructed using quadratic regression (weighted 1/concentration
