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

backgroundEndothelial cell activation may be connected with the pathogenesis of delayed cerebral ischaemia (DCI) after subarachnoid haemorrhage (SAH).

aimTo assess the relationship between serial concentrations of circulating markers of endothelial cell activation (soluble intercellular adhesion molecule-1, soluble platelet selectin (sP-selectin), soluble endothelial selectin, ED1-fibronectin, Von Willebrand Factor (VWF) and VWF propeptide) and development of DCI.

methods687 blood samples were collected from 106 consecutive patients admitted within 72 h after onset of SAH. Changes in levels were analysed in the last sample before and in the first sample after the onset of DCI (n = 30), and in subgroups with DCI occurring within 24 h after treatment of the aneurysm (n = 12) or unrelated to treatment of the aneurysm (n = 18). Patients without DCI (n = 56) served as controls.

resultsConcentrations of sP-selectin, but not of the other markers, were found to increase considerably after DCI unrelated to treatment of the aneurysm (increase 25 ng/ml, 95% CI 8 to 43), whereas they tended to decrease in the control patients without DCI (decrease 13 ng/ml, 95% CI -28 to 2.4). Surgery was found to profoundly influence the levels of the markers irrespective of the occurrence of DCI.

conclusionThe rise in sP-selectin level during DCI is suggested to be the result of platelet activation, as levels of the other markers of endothelial cell activation were not increased after DCI unrelated to treatment. Whether a causal role of platelet activation is implicated in the development of DCI should be determined in further studies in which the relationship between concentrations of markers and treatment is taken into account.
