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 simple LC-MS/MS method for the quantitative determination of the norepinephrine analogue meta-iodobenzyl-guanidine (mIBG) was developed and validated for mouse plasma and tissues, including salivary gland and heart. The assay procedure involved a one-step solvent extraction of mIBG and the internal standard N-(4-fluorobenzyl)-guandine from plasma or tissue homogenates with acetonitrile. An Accucore aQ column was used to separate analytes using a gradient elution with a total run time of 3.5 min. Validation studies with quality control samples processed on consecutive days revealed values for intra-day and inter-day precision of < 11.3%, with values for accuracy ranging 96.8-111%. Linear responses were observed over the entire calibration curves range (up to 100 ng/mL), and the lower limit of quantification was 0.1 ng/mL, using sample volumes of 5 µL. The developed method was successfully applied to evaluate the plasma pharmacokinetics and tissue distribution of mIBG in wild-type mice and animals lacking the organic cation transporters OCT1, OCT2, OCT3, and/or MATE1 to further understand mechanisms contributing to drug distribution and elimination and causes of inter-individual pharmacokinetic variability.
