Rapid multiplex PCR assays in patients with respiratory viral infections: is semi-quantitative data useful? A pilot study.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Viral respiratory rapid multiplex PCR assays FilmArray® (FA) and ePlex® (eP) provide qualitative results which may not reflect clinical relevance. In a pilot study, we report retrospectively whether the semi-quantitative PCR assay R-GENE® would have facilitated clinical interpretation. Forty-four patients were hospitalized for various respiratory manifestations; all of them have benefited from a respiratory sample during acute symptoms. Among the 44 patients, FA detected 23 positive samples including 31 viruses, 26 of them gave high or moderate R-GENE® scores (cycle threshold < 35), and all but one were consistent with clinical history. Semi-quantitative scores would have allowed for critical interpretation of the results; those are a key additional element for an optimal exploitation of the rapid multiplex PCR assays power.
