Toxicological investigations in a death involving 2-MAPB.
Article in Forensic science, medicine, and pathology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
New psychoactive substances are becoming increasingly popular. However, there is a lack of mass spectral information on parent substances and their corresponding metabolites as well as fatal concentrations in body liquids and tissues. Only very few clinical reports and user reports exist. This is also the case for methylaminopropylbenzofuran (MAPB) isomers. Urine from a decedent was screened using different immuno assays, gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-high resolution mass spectrometry (LC-HRMS/MS). Additionally, respective targets were quantitated in all analyzed specimens by LC-MS/MS. Gas chromatography-infrared spectroscopy (GC-IR) was applied to confirm the identity of the intoxication. GC-MS and the amphetamine immuno assay were useful to track the putative intoxication. However, the chemical structure of 2-MAPB was only elucidated by means of LC-HRMS/MS and GC-IR. 2-MAPB was highest in urine (167 µg/mL), followed by gastric content (98.9 µg/mL), bile fluid (30.8 µg/mL), liver (22.2 µg/g), heart blood (16.7 µg/mL), and lowest in femoral blood (7.3 µg/mL). Besides the parent substance, we detected N-demethyl-2-MAPB and hydroxy-2-MAPB in the urine sample. This case report presents an intoxication caused by 2-MAPB. The 2-MAPB concentration found in femoral blood exceeded those reviewed for 5/6-MAPB. The concentrations of the other specimens cannot be evaluated because there exist no comparative data. The values presented can be applied to assess 2-MAPB intoxications in the future.
