Ratiometric fluorescence probes for visible detection and accurate identification of MPEA vapor.
Article in Nature communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Methamphetamine (MA), as one kind of overflowed synthetic illicit drugs, has posed severe threats to health and social security. However, the on-site and visible fluorescence detection to MA remains limited. Herein, through covalently coupling diphenylacridine (DPA) and dimethylacridine (DMA) with pyridine, two ratiometric fluorescence probes (PyDPA and PyDMA) are constructed, which present rapid response, bathochromic-shifts over 100 nm and visible fluorescence color changes from blue to cyan upon the exposure to methylphenethylamine (MPEA, a simulant of MA). And the similar responses are observed for MA in confiscated samples. Further, a smartphone-based quantitative detected system is established to provide the on-site trace detection of MPEA as ppb level. Specially, PyDPA or PyDMA can identify MPEA from its interferences according to the unique ratiometric response based on their dual-emission-enhancement. Here, we show two ratiometric fluorescence probes to MA and MPEA with high potential for on-site application.
