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

backgroundStroke-associated pneumonia (SAP) is a common infectious complication of acute ischemic stroke (AIS). Although numerous predictive models for SAP have been proposed, a more objective and easily applicable marker is required. This study evaluated the association between the red cell index (RCI) and SAP in patients with AIS.

methodsWe analyzed 500 consecutive patients with AIS. SAP was defined based on modified Centers for Disease Control and Prevention criteria. The RCI was calculated using blood sample results according to the following formula: RCI = (red blood cell count [⋅10

conclusionWe demonstrated that a higher RCI was associated with SAP in patients with AIS. Furthermore, elevated RCI was associated with worse outcomes in patients who developed SAP.
