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

purposeTo identify patient- and procedure-related factors associated with radiation exposure during middle meningeal artery (MMA) embolization for chronic subdural hematoma (cSDH), with particular focus on embolic agent (particle vs. liquid) and arterial access route (transradial vs. transfemoral).

methodsIn this retrospective single-center cohort study, we included all patients who underwent MMA embolization for cSDH between February 2021 and October 2025. MMA embolization was performed by fourteen experienced board-certified neuroradiologists. The primary outcome was dose area product (DAP, Gy · cm

resultsA total of 112 patients (median age 81 years; 20% female) were included; 69 (62%) underwent embolization with particles and 43 (38%) with liquid agents. Transradial access was used in 17 (15%) and transfemoral access in 95 (85%) procedures. Overall median (IQR) DAP was 74.7 Gy · cm

conclusionIn MMA embolization for cSDH, radiation exposure is primarily driven by procedural extent, with higher DAP in bilateral than in unilateral embolization, whereas the choice of embolic material and arterial access route is not associated with radiation dose. These findings support selecting embolic agents and access routes based on anatomical and clinical considerations rather than radiation concerns.
