1 · What the graph read from it

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.

2 · The registry

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

purposeEndoscopic retrograde cholangiopancreatography (ERCP) is widely used in the management of pancreaticobiliary disorders and may be associated with systemic oxidative stress. Dynamic thiol-disulfide homeostasis, which reflects the balance between reduced and oxidized thiol groups, has emerged as a sensitive indicator of systemic redox status. This study aimed to evaluate alterations in thiol-disulfide homeostasis in patients undergoing ERCP.

methodsIn this observational study, patients undergoing ERCP and control subjects were included. Serum native thiol, total thiol, disulfide levels, and thiol-based ratios were measured using an automated spectrophotometric assay. Baseline demographic and laboratory characteristics were compared between groups. Age-adjusted analyses were performed using analysis of covariance (ANCOVA), and longitudinal changes were evaluated using mixed-effects models.

resultsCompared with controls, patients undergoing ERCP demonstrated significantly lower native thiol and total thiol levels together with higher disulfide concentrations and altered thiol-based ratios. Age-adjusted analyses confirmed significant group effects for native thiol, total thiol, disulfide, and native thiol/total thiol ratio. Longitudinal analyses showed partial increases in reduced thiol parameters after ERCP; however, post-procedural values remained lower than those observed in controls at the 24-h time point. These alterations were observed irrespective of post-ERCP pancreatitis or pancreatic enzyme elevations.

conclusionPatients undergoing ERCP exhibited significant alterations in thiol-disulfide homeostasis, characterized predominantly by depletion of reduced thiol pools. The observed redox imbalance persisted during the early post-procedural period and appeared to be associated with both underlying pancreaticobiliary disease and procedure-related oxidative stress. Further studies are needed to clarify the clinical significance of these findings.
