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
Faced with the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), high-throughput respiratory tests are in high demand. We evaluated the clinical performance of the GSD NovaPrime® SARS-CoV-2 RTq-PCR assay, a new assay that detects 2 specific RNA sequences of the nucleocapsid (N) gene. It was assessed using 99 nasopharyngeal samples and compared in parallel with the Allplex® assay. Among those samples, 72 and 27 were included in the positive (PPA) and negative (NPA) percent agreement analyses, respectively. In case of discordance, samples were reanalyzed with another amplification technique, the Aptima® SARS-CoV-2 assay. Cross-reactivity, including specimens positive for another respiratory virus and collected before the COVID-19 outbreak, was also evaluated (n = 32). Based on the patients' clinical history, the Ct (cycle threshold) values obtained, and the results of the Aptima® assay, the clinical performances were deemed satisfactory, with the PPA reaching a minimum percentage of 87.5% and the NPA reaching 100%. No cross-reactivity with other respiratory viruses was observed.
