Evaluating the Reliability of Dipstick Drug Screens on Vitreous and Postmortem Blood as a Triage Modality in Forensic Pathology.

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
Dipstick drug screens are cheap, easy to use, and quick presumptive tests to detect common drugs of abuse. Dipsticks are designed for drug detection in urine. There is no literature regarding their potential use on fluids different from urine. The study aimed to determine the performance of dipstick screening tests on postmortem vitreous and blood specimens compared to urine dipsticks and final confirmatory toxicology analyses on blood. The study population included cases in which a complete toxicology analysis was performed. Each subject was screened for three substances: cocaine, fentanyl, and opiates. Dipstick results were checked by visual inspection. Results were compared with urine screening tests and quantitative, confirmatory toxicological analyses by gas chromatography/mass spectrometry on postmortem blood samples as the gold standards for screening and confirmatory analysis, respectively. There was a high number of false-negative results for opiates. Cocaine dipsticks in blood showed the highest reliability. Fentanyl dipsticks in vitreous showed a high number of false-negative results. Both vitreous and blood dipstick screening tests for all substances performed well on negative cases. When both blood and vitreous screening tests are negative, the chance that the confirmatory toxicology analysis will be positive is very low.
