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
backgroundThis study aimed to evaluate the diagnostic utility of metagenomic next-generation sequencing (mNGS) in detecting pulmonary infections in persons living with HIV(PLWH).
methodsWe conducted a retrospective study involving 246 PLWH with pulmonary infections. Bronchoalveolar lavage fluid (BALF) specimens were collected from all patients. mNGS and traditional microbial cultures were performed in parallel to compare the differences in pathogen identification. Patients were stratified by immune status based on CD4
resultsmNGS demonstrated a significantly higher pathogen detection sensitivity (98.0%) compared to traditional cultures (32.1%). The spectrum of pathogens detected by mNGS and culture methods differed significantly. mNGS identified 123 pathogenic microorganisms, whereas cultures detected only 17. mNGS detected additional pathogens, including viruses (e.g., Epstein-Barr virus and cytomegalovirus) and fastidious microorganisms (e.g., Pneumocystis jirovecii). Furthermore, mNGS revealed a significant correlation between PLWH-associated immunodeficiency and pathogen profiles. The diversity of pathogens, particularly fungi and viruses, increased with declining CD4
conclusionmNGS comprehensively characterizes the complex pathogen spectrum in PLWH-associated pulmonary infections, significantly enhancing detection sensitivity for mixed and fastidious infections, thereby guiding targeted anti-infective therapy. Immunosuppression severity strongly correlates with opportunistic pathogen profiles and the risk of specific pathogen detection, highlighting the importance of immune status-guided clinical strategies. mNGS serves as a valuable adjunct to conventional diagnostic methods, enhancing the detection and prognostic assessment of infectious complications in PLWH.
