Immediate perioperative safety and resource utilization of stand-alone middle meningeal artery embolization and stand-alone surgical evacuation for chronic subdural hematoma.

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
ObjectiveRandomized trials will ultimately determine whether stand-alone middle meningeal artery embolization (MMAE) is effective in preventing the recurrence of chronic subdural hematoma (cSDH). We therefore characterized in-hospital complications, length of stay, and discharge disposition among adults undergoing stand-alone MMAE for non-traumatic cSDH in the United States.MethodsWe conducted a retrospective cohort analysis using the National Inpatient Sample (2016-2022) to identify adult patients (≥18 years) with a primary diagnosis of nontraumatic cSDH. Primary outcomes included inpatient complications, non-home discharge (NHD), and extended length of stay (eLOS). 1:5 Propensity score matching (PSM) and multivariable regression were adjusted for baseline differences, including demographics, frailty (mFI-5), illness severity (APR-DRG subclass), and comorbidities. Presenting symptomatology (encephalopathy, gait instability, weakness, headache, etc.) was incorporated into both matching and regression models.ResultsOf 65,340 patients, 3390 (5.2%) underwent MMAE and 61,950 (94.8%) underwent surgery. After PSM, 1740 MMAE and 6525 surgical patients were analyzed. Following adjustment for demographics, frailty, illness severity, comorbidities, and presenting symptoms, standalone surgery remained significantly associated with increased inpatient morbidity and resource utilization. Compared to MMAE, surgery carried 1.8x the odds of any complication (
