Disposable electrochemical immunosensor array for the multiplexed detection of the drug metabolites morphine, tetrahydrocannabinol and benzoylecgonine.
Article in Mikrochimica acta, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Heroin, marijuana and cocaine are widely abused drugs. Their use can be readily detected by analyzing urine for the metabolites morphine (MOR), tetrahydrocannabinol (THC) or benzoylecgonine (BZC). A multiplex immunosensor is described here for detection of MOR, THC and BZC using screen printed carbon array electrodes modified with gold nanoparticles. Antibodies against MOR, THC and BZC were immobilized on eight electrodes in a sensor array simultaneously, and a competitive assay was used for the detection. The free analytes in the sample compete with bovine serum albumin-conjugated analytes for the immobilized antibodies on the sensor surface. The array is capable of detecting the three drugs simultaneously within 20-40 min. The method has a high sensitivity, with detection limits as low as 1.2, 7.0, and 8.0 pg.mL
