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

backgroundAlthough subarachnoid hemorrhage-related mortality has decreased in recent years due to improvements in treatment, data on the evolution of 1-year functional outcomes after subarachnoid hemorrhage are lacking. The objective of this study was to evaluate the evolution of patient management and their functional outcomes 1 year after subarachnoid hemorrhage over time in a single high-volume neurosurgical intensive care unit.

methodsIn this observational retrospective study, all consecutive patients with aneurysmal subarachnoid hemorrhage admitted to our neurosurgical intensive care unit between 2002 and 2019 were included. A poor functional outcome was defined as a modified Rankin Scale score of 4-6. Linear regressions were performed, and relative risk reductions of a poor functional outcome were calculated.

resultsBetween 2002 and 2019, 1556 patients were included, of whom 329 (21%) had a poor functional outcome. Over time, the percentage of coiling procedures (p = 0.004) increased, and the percentage of delayed cerebral ischemia (p = 0.03) decreased. One-year mortality decreased over time (p < 0.001), whereas 1-year functional outcome improved (p = 0.002), with a relative risk reduction of poor functional outcomes of 38% (17-54%).

conclusionsThe 1-year functional outcome of patients with subarachnoid hemorrhage improved between 2002 and 2019, and mortality decreased.
