Comparison of proximal coil embolization versus distal middle meningeal artery embolization for the treatment of chronic subdural hematomas.

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
Background: Multiple trials have recently been published evaluating middle meningeal artery embolization (MMAE) for the treatment of chronic subdural hematomas (SDHs). All trials, however, have assessed distal embolization with liquid embolic while many retrospective reviews have evaluated distal embolization with polyvinyl alcohol (PVA) particles. The present study sought to compare the efficacy and safety of proximal coil MMAE with the efficacy and safety of distal embolization. Methods: A prospectively collected, retrospectively analyzed database was queried for patients undergoing MMAE. Patients were subdivided into cohorts based on treatment modality: distal embolization with PVA particles or proximal coil embolization. The electronic medical record was reviewed to obtain demographic, surgical, and outcome data, and these data were compared. Additional subgroups were created to separately compare patients undergoing only embolization as well as patients undergoing surgical decompression with embolization. Results: Ninety-five patients with 122 SDH were identified. No significant difference was identified between groups demographically; however, there was a significant decrease in fluoroscopy with unilateral proximal embolization (14.0 min vs. 17.2 min, Conclusion: Proximal MMAE is noninferior to distal embolization with a decrease in fluoroscopy time and a potential reduction in embolic complications.
