Kogene PowerChek Multiplex Real-time PCR Kits Versus the BioFire FilmArray Gastrointestinal Panel: Roles of Crossing Point Values and Melting Curves in Interpreting the FilmArray Gastrointestinal Panel.
Article in Annals of laboratory medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Various molecular methods are used to rapidly detect gastrointestinal pathogens, highlighting the importance of understanding the performance of the associated kits in detail. We comprehensively assessed the performance of Kogene PowerChek multiplex real-time PCR kits (PowerChek Bacterial/Viral Kits) with the FilmArray GI Panel. Methods: Residual stool specimens (N=246), initially tested utilizing the FilmArray GI Panel (May 2023-Jan 2024), were reanalyzed using PowerChek Bacterial/Viral Kits. Discrepancies were resolved by performing additional molecular assays and reviewing culture results when available. True positives (TPs)/true negatives were defined by concordant results in at least two assays. We determined cycle threshold (Ct)/crossing point (Cp) distributions between the TP and false positive (FP) groups and analyzed melting curves for the FilmArray GI Panel FPs. Results: The positive-percent agreement (PPA) of the PowerChek Bacterial/Viral Kits was 50-100%, with lower values for Conclusions: The FilmArray GI Panel demonstrated higher sensitivity than the PowerChek Kits. For norovirus, melting curve analysis will help avoid FPs.
