Development and Validation of a Rapid Point-of-Care CYP2C19 Genotyping Platform.
Article in The Journal of molecular diagnostics : JMD, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Pharmacogenetic-guided prescribing can lead to more accurate medicine selection and dosing, improving patient outcomes and leading to better use of health care budgets. Loss-of-function variants in CYP2C19 influence an individual's ability to metabolize clopidogrel, increasing the risk of secondary vascular events following ischemic stroke and percutaneous coronary intervention. In acute clinical contexts, centralized laboratory-based testing is too slow to inform timely clinical decision-making. This work reports the development and analytical validation of the Genedrive CYP2C19 ID Kit, which provides rapid point-of-care genotyping from a buccal swab in approximately 1 hour. Buccal samples were collected from a total of 204 individuals between September 2023 and July 2024, alongside a blood or saliva sample for comparison with laboratory testing. In the final cohort of 202 patients, all point-of-care results were concordant with laboratory testing. In this assessment, the sensitivity and specificity of the CYP2C19 ID Kit was 100% (95% CI, 95.0%-100%) and 100% (95% CI, 97.2%-100%), respectively. The failure rate of the CYP2C19 ID Kit was 0.98%. This study confirms the analytical validity of the Genedrive CYP2C19 ID Kit. The Genedrive system is able to provide an accurate, rapid, noninvasive alternative to standard laboratory testing and can be used as a point-of-care test in the clinical environment.
