Regional Variation in the Management of Nontraumatic Subdural Hematomas Across the United States.
Observational study in World neurosurgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgoundNontraumatic subdural hematomas are a common indication for inpatient hospitalization in the United States, yet there is little high-quality evidence regarding which patients should receive surgical or medical treatment. We sought to assess variation in surgical management and medical treatment with steroids for nontraumatic subdural hematomas across the United States.
methodsUsing the Premier database, we analyzed patients with a primary discharge diagnosis of nontraumatic subdural hematoma in 2014. International Classification of Diseases, Ninth Revision, procedure codes were used to identify patients who underwent surgical management, and pharmacy data were used to identify patients treated with dexamethasone. Univariable and multivariable analyses were used to examine the association of age, race, sex, academic versus nonacademic center, and regions of the United States with conservative or surgical management.
resultsThere were 3915 inpatient hospitalizations for nontraumatic subdural hematomas in 2014 in the Premier database, of whom 1860 (47.5%) underwent surgery, and 360 (9.2%) underwent treatment with dexamethasone, either as a primary treatment or as an adjuvant to surgery. Older age, female sex, and being managed outside of the Western U.S. region were associated with a lower likelihood of undergoing surgical management on multivariable analysis; only younger age was associated with a greater likelihood of being treated with dexamethasone.
conclusionsThere is considerable variability in surgical management of nontraumatic subdural hematomas across the United States based on age, sex, and region. Future studies should explore the reasons for the variability and attempt to better clarify indications for surgical management of subdural hematomas.
