Colorimetric-Electrochemical Combined Method for the Identification of Drugs of Abuse in Blotter Papers: A Powerful Screening Technique Using Three Analytical Responses.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Lysergic acid diethylamide (LSD) and phenylethylamine derivatives (NBOHs and NBOMes) are commonly found on seized blotter papers, posing public health risks. Efficient screening methods for identifying these substances are currently limited. To address this, a novel protocol combining colorimetric and electrochemical techniques was developed as a screening method for drugs of abuse in blotter papers. The method uses Emerson's colorimetric reagent (CR) for NBOH identification combined with voltammetric detection via differential pulse stripping adsorptive voltammetry (AdSDPV) using graphite screen-printed electrodes (SPE-Gr). This approach offers, for the first time, an unambiguous identification of NBOHs through three analytical responses: (1) a color change following the addition of the CR; (2) an electrochemical signal indicating the NBOHs' redox process; and (3) a selective electrochemical signal of the colorimetric reaction product (CR-NBOH) on SPE-Gr. It also differentiates NBOH, NBOMes, 2Cs, and LSD, enabling rapid identification of drugs commonly found in blotter papers. Compared to previous sensors, this method provides selective detection of these drugs at the same pH, offering simplicity for forensic applications. The proposed method showed strong electrochemical stability with low variability (<2.3% RSD) and a low detection limit (0.3 μg mL
