Assessment of Test Performance and Potential for Environmental Contamination Associated with a Point-of-Care Molecular Assay for Group A
Article in Journal of clinical microbiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Although U.S. Food and Drug Administration-approved and CLIA-waived point-of-care (POC) molecular systems are being implemented in routine clinical practice, instrument reliability, test performance in the hands of end users, and the potential for environmental contamination resulting from use of POC molecular systems have not been extensively evaluated. We performed a prospective evaluation of the Roche cobas Liat group A streptococcus (GAS) assay compared to routine real-time PCR. We evaluated test accuracy, instrument failure rate, and monitored for environmental contamination when testing was performed by minimally trained end users in an Express Care Clinic environment. The overall concordance of the Liat GAS assay with routine testing was 97.2% (455/468). The average Liat failure rate across three analyzers was 6.6% (33/501) (range, 3.7 to 11.6%), and no environmental contamination was detected during the course of the study. The cobas Liat platform and GAS assay demonstrated reliable performance in the end user setting and may serve as a rapid, POC option for routine diagnostic testing for certain infectious diseases, including GAS.
