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
Pyogenic liver abscess (PLA) is a serious intra-abdominal infection with high morbidity and mortality. Current diagnostic methods are time-consuming, inefficient and high-cost. Rapid identification/assessment of PLA and early recognition of bacterial liver abscess (BLA) improve prognosis. Iron metabolism disorders play a critical role in infections, but their role in PLA (especially ferritin) remains unclear. Notably, dietary nutrition, as a modulator of iron metabolism/immune function, may influence PLA progression, with limited research. In this study, we collected clinical data of 125 PLA patients from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database to identify rapid, low-cost severity biomarkers, and verified them by an independent clinical cohort of 36 patients from Peking University Third Hospital. We analyzed the correlation between iron metabolism and disease severity, explored independent risk factors, and evaluated diagnostic efficiency via receiver operating characteristic (ROC) curves. Iron metabolism disorders were observed in patients with PLA and correlated strongly with liver dysfunction and systemic inflammation. Ferritin was associated with disease severity and served as an independent prognostic marker, with optimal cut-offs of 390 ng/mL for predicting severe PLA and 748 ng/mL for identifying BLA. This study identifies ferritin as a promising multifaceted biomarker for PLA which not only reflects disease severity but also aids in the early identification of bacterial etiology. Additionally, the findings provide a basis for dietary nutritional interventions in PLA management.
