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

Animal models are established to display the pathophysiological changes following subarachnoid hemorrhage (SAH). The aim of the present study was to determine case fatality in mouse delayed cerebral ischemia (DCI) models, to compare mortality in mouse DCI models to case fatality in human SAH patients, and to identify factors influencing mouse mortality. A systematic search of the PubMed database was performed to identify all studies that assessed mouse DCI models. Mortality rates and predictor variables were extracted and compared to the human case fatality after SAH as previously reported. Predictors for mouse mortality were identified through multivariate analysis. Forty-eight studies were included in the quantitative analysis. The mean overall mortality rate was 21% in mouse DCI models. However, the time period between induction of SAH and evaluation of mortality rates is a significant variable influencing the mortality rate in mouse SAH models. The experimental SAH model was the only significant predictor for mouse mortality after 48 h. In contrast, neither the genetic background nor the anesthetic changed the case fatality rate. Mouse mortality at 24, 48, and 72 h after experimental SAH in DCI models was significantly lower than human case fatality following aneurysmal SAH. The mean overall mortality rate in mouse DCI models is significantly lower than human case fatality following aneurysmal SAH. However, time between SAH induction and evaluation is a significant variable influencing the mortality rate in mouse SAH models. Further analyses will be required to establish whether and to which extent different DCI models affect mortality and reflect human pathophysiology.
