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

backgroundPatient differences from optimal mean arterial pressure (MAP

methodsThis was a retrospective single-center study of six patients with aSAH with simultaneous near-infrared spectroscopy, intracranial pressure, and MAP monitoring. Repeated-measures Pearson correlation and Bland-Altman plot analysis were performed to compare PRx and COx_a and to compare PRx-derived MAP

resultsRepeated-measures Pearson correlation analysis showed no correlation between PRx and COx_a (r = 0.06, p < 0.01). The correlation between PRx- and COx_a-derived MAP

conclusionsThe threshold applied to PRx should not be applied to COx_a. It is suggested to consider higher thresholds for COx_a than PRx in deriving the range for MAP
