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
Wood smoke exposure poses significant health risks, particularly in occupations such as firefighting, where short-term exposure to high levels of pollutants is common. The biomonitoring of wood smoke-associated biomarkers is crucial for assessing human exposure. S-phenylmercapturic acid (S-PMA), a key metabolite of benzene, has been widely used as a reliable biomarker for this purpose. However, current S-PMA detection methods lack the speed, portability, and user-friendliness required for widespread, on-site applications. In this study, we propose a novel detection system that integrates mesoporous Pd@Pt nanoparticle-mediated lateral flow immunoassay (LFIA) with a 3D-printed smartphone-based reader for detecting S-PMA. Performance testing with S-PMA in phosphate-buffered saline and spiked urine samples yielded limits of detection of 0.5 ng/mL and 2.5 ng/mL, respectively. The use of mesoporous Pd@Pt nanoparticles as signal amplifiers for LFIA, along with the integration of a 3D-printed device for accurate image acquisition, significantly enhanced the system's sensitivity, achieving detection limits well below the threshold recommended by the American Conference of Governmental and Industrial Hygienists. With remarkable stability and reproducibility, our method provides a noninvasive, highly sensitive, rapid, portable, low-cost, and user-friendly solution for the on-site assessment of wood smoke exposure in occupational settings, laying the foundation for future innovations in real-time environmental exposure monitoring.
