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

BACKGROUND AND

objectivesChronic subdural hematoma (CSDH) management is evolving with the increasing use of middle meningeal artery embolization (MMAE). Limited data exist on the time to resolution (TTR) across different interventions. The aim of this study was to establish a baseline TTR for surgically treated CSDHs before MMAE implementation and compare it with TTR of MMAE.

methodsA retrospective analysis of 94 surgically treated CSDHs in 75 patients was performed. Kaplan-Meier survival analysis was used to model TTR for patients undergoing burr hole craniostomy (BHC), craniotomy, and twist drill craniostomy/subdural evacuating port system placement. Univariate and multivariate Cox regression analyses were performed to identify predictors of TTR. An unmatched cohort of 43 patients undergoing MMAE alone was underwent TTR analysis and compared with the surgical arm.

resultsThe median TTR for surgically treated CSDHs was 11 weeks, without significant difference between BHC and craniotomy groups. The median TTR for MMAE-treated patients was 14 weeks, significantly longer than craniotomy (

conclusionResolution of CSDH commonly requires several months regardless of intervention type. Radiographic and clinical follow-up is widely variable. Although decompressive strategies achieve faster relief of mass effect and symptoms, interventions should consider the TTR and ability of patient to follow-up. Recognition of CSDH as a sentinel health event emphasizes the need for individualized treatment and long-term follow-up strategies.
