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

backgroundAnimal studies describe changes in the spleen following a stroke, with an immediate reduction in volume associated with changes in the counts of specific blood white blood cell (WBCs). This brain-spleen cell cycling after stroke affects systemic inflammation and the brain inflammatory milieu and may be a target for emerging therapeutic studies. This study aimed to evaluate features of this brain-spleen model in human patients admitted for acute stroke.

methodsMedical and imaging records were retrospectively reviewed for 82 consecutive patients admitted for acute stroke in whom an abdominal computed tomography scan was performed.

resultsMean ± SD splenic volume was 224.5 ± 135.5 cc. Splenic volume varied according to gender (P = .014) but not stroke subtype (ischemic versus hemorrhagic, P = .76). The change in splenic volume over time was biphasic (P = .04), with splenic volumes initially decreasing over time, reaching a nadir 48 hours after stroke onset, then increasing thereafter. Splenic volume was related inversely to percent blood lymphocytes (r = -.36, P = .001) and positively to percent blood neutrophils (r = .30, P = .006).

conclusionsCurrent results support that several features of brain-spleen cell cycling after stroke described in preclinical studies extend to human subjects, including the immediate contraction of splenic volume associated with proportionate changes in blood WBC counts. Splenic volume may be useful as a biomarker of systemic inflammatory events in clinical trials of interventions targeting the immune system after stroke.
