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

Introduction: Middle meningeal artery embolization is a treatment option for chronic subdural hematoma (cSDH), but data on post-procedural imaging interpretation remain limited. This study investigates whether specific enhancement patterns can predict radiological outcomes and evaluates the utility of photon-counting computed tomography (PCCT) in distinguishing contrast enhancement from hemorrhage. Methods: We retrospectively analyzed 105 cSDHs imaged with either PCCT or flat-panel CT immediately after embolization. Two independent raters assessed enhancement patterns; diagnostic confidence and interrater agreement were evaluated. Results: PCCT demonstrated higher diagnostic confidence and interrater reliability than flat-panel CT. Internal enhancement and fluid-fluid levels were significantly associated with hematoma persistence or recurrence. Discussion: PCCT enhances post-embolization imaging assessment in cSDH. Specific enhancement patterns may serve as imaging biomarkers to identify patients at increased risk for unfavorable radiological outcomes.
