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

Chronic subdural hematoma (CSDH) is common, especially in patients over 50 years of age, and represents about 10% of all intracranial hematomas. The pathogenesis, diagnosis, and treatment of CSDH are controversial. The purpose of this study was to document the clinical application of a novel imaging classification system for the neuroendoscopic treatment of CSDH. This was a prospective study of sixty patients who underwent neuroendoscopic CSDH treatment beginning in January 2017, with a 6-month follow-up. Hematomas were classified into two types based on imaging features: simple (type I) and complex (type II). Complex type was further subclassified as septated (type II-A), stratified (type II-B), recurrent (type II-C), thin-layer (type II-D), bilateral (type II-E), or mixed (type II-F). Most hematomas were located on the left side. Type II hematomas had fibrous septa and bridging veins in the cavities. Bender classification and Glasgow Outcome Scale (GOS) scores were improved after neuroendoscopic surgery and hematoma thickness was improved significantly in all CSDHs on days 1, 7, and 14 after surgery (all
