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
Bongkrekic acid (BKA) poisoning is a severe foodborne illness with a high mortality rate. This study aimed to identify BKA in postmortem tissues from poisoning victims in Taiwan and to develop a reliable analytical method for detecting BKA in biofluids to aid clinical diagnosis and treatment. BKA was identified in postmortem samples using high-resolution mass spectrometry (HRMS) and confirmed with an independent ultrahigh-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) method. To meet clinical needs, a UHPLC-MS/MS method was developed and validated for BKA detection in plasma and urine. Method optimization included adjustments to ion source conditions for multiple reaction monitoring (MRM) transitions and avoidance of glass vials due to BKA adsorption onto free silanol groups. Chromatographic separation was achieved using a 50-mm Hypersil Gold C18 column within a 6-min run time. The validated UHPLC-MS/MS method successfully detected BKA in biofluids, enabling its application in identifying victims of foodborne poisoning. The method demonstrated high accuracy and efficiency, facilitating timely diagnosis and aiding in treatment strategies for critically ill patients. The developed UHPLC-MS/MS method provides a reliable approach for detecting BKA in clinical and forensic settings. Its implementation enhances diagnostic capabilities, improves patient outcomes, and supports monitoring of toxin elimination in cases of BKA poisoning.
