Plasma ddPCR for etiological diagnosis of focal bacterial infections.
Article in Frontiers in medicine, 2025. 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
Background: Plasma droplet digital polymerase chain reaction (ddPCR) has been used for pathogen detection and has shown good diagnostic value, but no studies have yet demonstrated its application in focal infections. Herein a pilot study using plasma ddPCR to diagnose focal infection is discussed. Methods: Eight patients with a diagnosed focal infection who underwent plasma ddPCR for bacterial detection between 2021 and 2022 in Sir Run Run Shaw hospital were enrolled in this retrospective single-center pilot study. Results of ddPCR and focal cultures were compared as well as the turnaround time of two methods and other clinical data. Results: In 7/8 cases, plasma ddPCR results were consistent with focal culture results. The turnaround time for ddPCR was 2.5 h, significantly lower than the average time for focal cultures of 2.63 days. Conclusion: This pilot study indicates the promising value of the plasma ddPCR method in the rapid diagnosis of focal infection. If larger studies support the findings here, this method can help improve diagnostic accuracy and guide treatment decisions in suspected focal infections.
