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
Diagnosing pulmonary tuberculosis (TB) and monitoring treatment remain challenging. New tools such as the PATHFAST TB LAM assay (PHC Corporation, formerly LSI Medience Corporation, Tokyo, Japan; distributed by BioSynex, France; PF-LAM) may complement microscopy, culture, and NAAT. PF-LAM is an immunoassay quantifying lipoarabinomannan (LAM), a mycobacterial cell wall component, in sputum within 1 hour using an automated chemiluminescent reader. Diagnostic performance was first assessed on 100 sputum samples: 40 culture-positive for IMPORTANCE: Effective monitoring of the treatment response is essential for successful tuberculosis (TB) management as prolonged therapies require accurate evaluation to prevent relapse, treatment failure, or drug resistance. This study highlights the diagnostic and treatment-monitoring potential of the PATHFAST TB LAM Ag assay, which quantifies lipoarabinomannan (LAM) concentrations in sputum samples and correlates with bacterial load. For the first time, we also demonstrate the assay's applicability for detecting and monitoring nontuberculous mycobacterial (NTM) pulmonary diseases, which are increasingly prevalent in industrialized countries. The semi-automated, rapid format (<17 minutes) of the PATHFAST TB LAM Ag assay provides a simple and reliable approach for assessing bacillary load during treatment, representing a promising tool for improving patient management and diagnostic efficiency in both TB and NTM-PD.
