Pathogen-oriented targeted next-generation sequencing as an adjunctive tool for detection of pathogens in endophthalmitis: a retrospective clinical evaluation.
Article in Frontiers in medicine, 2026. 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: Endophthalmitis represents one of the most severe ophthalmic emergencies, requiring prompt etiological identification to enable tailored antibiotic administration. Conventional identification methods, such as ocular sample culture, exhibit limited positivity in endophthalmitis, necessitating more advanced approaches. Methods: The performance of pathogen-oriented targeted next-generation sequencing (tNGS), designed to capture a predefined panel of 207 clinically relevant pathogens, was retrospectively evaluated in 43 patients with endophthalmitis. Results: The positivity rate of culture was 22.2% (8/36, 95% CI: 10.1-39.2%), whereas that of tNGS was 86.0% (37/43, 95% CI, 72.1-94.7%). tNGS had a turnaround time of less than 24 h, facilitated the detection of polymicrobial infection, and identified microbes in 91.7% (11/12) of specimens that were negative for both smear and culture. Among the 36 paired specimens subjected to both culture and tNGS, tNGS achieved microbial identification in 25 of 28 culture-negative specimens (89.3%), and its positivity rate (88.9%, 32/36, 95% CI, 73.9-96.9%) was significantly higher than that of culture ( Conclusion: The higher positivity and shorter turnaround time of pathogen-oriented tNGS render it an adjunctive tool for enhancing pathogen identification in endophthalmitis. We recommend the routine application of tNGS as a valuable complement to culture, in order to facilitate and expedite pathogen detection, thereby advancing efforts toward tailored precision medicine in the management of endophthalmitis.
