Multiplex PCR-based rapid pathogen identification in acute cholecystitis using the FilmArray BCID2 panel.

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
Purpose: Acute biliary infections are serious conditions in which delayed or inappropriate therapy can worsen clinical outcomes and promote antimicrobial resistance. This study evaluated the FilmArray® Blood Culture Identification 2 (BCID2) panel, a multiplex PCR system, for the rapid detection of pathogens in bile samples from patients with acute cholecystitis. Methods: Bile samples were collected intraoperatively or by percutaneous aspiration from 77 consecutive patients with acute cholecystitis. Each specimen was divided for conventional culture and BCID2 panel testing. Culture results served as the reference standard to calculate positive and negative percent agreement (PPA and NPA), predictive values, and accuracy. Results: Bacterial growth was observed in 34 cases (44.2%), yielding 57 isolates from 16 species. The BCID2 panel correctly detected 41 of 46 BCID2-targetable isolates. For detecting at least one pathogen, PPA (sensitivity) was 82.4%, NPA (specificity) 100%, positive predictive value 100%, negative predictive value 91.5%, and overall accuracy 92.2%. Detection was achieved in 70.6% of monomicrobial and 94.1% of polymicrobial infections, with higher bacterial loads (>10 Conclusion: Multiplex PCR testing using BCID2 panel enables rapid and accurate identification of causative bacteria directly from bile. This approach may support earlier targeted therapy and promote appropriate antimicrobial stewardship in acute biliary infections.
