Twist drill craniostomy vs burr hole drainage of chronic subdural hematoma: a systematic review and meta-analysis.
Synthesis in Acta neurochirurgica, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06337851 (Comparing Simultaneous and Consecutive Drainage of Bilateral Chronic Subdural Hematoma), which is not on this map. Cited by 16 papers, 2 of them syntheses 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.

Abstract
introductionThere is a clinical equipoise between burr hole drainage (BHD) or twist drill craniotomy (TDC) as initial surgical intervention in patients with chronic subdural hematoma (cSDH). Moreover, the impact of type of postoperative drainage is not well elucidated. We performed a systematic review and meta-analysis comparing outcomes following BHD and TDC for initial surgical management in cSDH and to understand the impact of negative suction drainage with TDC.
methodsA literature search was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for studies that directly compared TDC and BHD. The following outcomes were compared between TDC and BHD: mortality, recurrence, reoperations, complications, and cure rates. Subgroup analysis was performed to determine impact of negative suction drainage with TDC.
resultsSixteen articles (n = 1,235; TDC: 663; BHD: 591) met inclusion criteria. Although complications (OR: 0.68, 95% CI: 0.38-1.23, p = 0.21; I
conclusionA systematic review and meta-analysis of available literature directly comparing TDC and BHD for primary evacuation of cSDH did not demonstrate clear superiority of either technique, although reoperations may be higher following TDC. Use of negative suction drainage with TDC may lead to similar rates of reoperation as BHD.
