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: This study aims to explore the performance of metagenomic next generation sequencing (mNGS) in the diagnosis of non-neutropenic invasive pulmonary aspergillosis (IPA) and its clinical application value. Methods: This multi-center study enrolled 293 suspected IPA patients who conducted mNGS from October 2020 to February 2024. These cases were classified into IPA group and non-IPA group according to IPA diagnostic criteria. We analyzed the diagnostic value of mNGS by comparing with sputum culture, BALF culture, serum and BALF GM test. Results: A total of 118 IPA patients (4 proven/113 probable/1 possible diagnosis) were included in our study. The most common Conclusion: mNGS demonstrated significant diagnostic value for IPA, exhibiting significantly higher sensitivity compared to current conventional microbiological tests while maintaining equivalent specificity. The combination of BALF mNGS with GM performed great sensitivity and negative predictive value. BALF specimens seemed to be superior to blood and sputum samples. However, for patients unable to undergo bronchoscopy, sputum and blood mNGS were still superior to other methods.
