Label-Free Detection of 2,4-Dinitrotoluene Using a Laser-Induced Graphene Based Chemiresistive Sensor.

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
The rapid and sensitive detection of nitroaromatic explosives is of paramount importance for both security and environmental monitoring. In this study, a label-free chemiresistive sensor based on laser-induced graphene (LIG) was developed for the selective detection of 2,4-dinitrotoluene (DNT). LIG films were directly fabricated on polyimide substrates via a single-step laser writing process, resulting in porous and conductive surfaces without additional modification. The structural, chemical, and electrical properties of the fabricated materials were comprehensively evaluated using scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS). The electrical properties were characterized by current-voltage (
