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

backgroundA subdural hematoma is defined as clot formation in the subdural space after vessel rupture or brain parenchyma damage. Several demographic and tomographic factors were associated to poor prognosis, although some debate according to their specific roles still remains.

methodsRetrospective cohort study of comatose patients admitted to a single-institution, tertiary hospital center, between the years 2013 and 2019 with traumatic acute subdural hematoma requiring surgical evacuation were studied. Demographic and tomographic data were obtained from medical records. Univariate and multivariate statistical analysis were performed, using a value of

resultsSeventy-seven patients were selected using the criteria and a total of 37 (48%) head CT exams were evaluated. The overall mortality was 57.1% and achieved 100% at ≥75-years-old subgroup. Univariate analysis only found young age as a good prognosis factor (

conclusionTraumatic acute subdural hematoma is a life-threatening condition. Younger age was the only positive prognostic factor identified. More research is necessary to establish age as a rule-out criterion to surgical indication.
