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

Atherosclerosis is the leading cause of death and serious morbidity in economically developed societies through its sequelae of coronary artery and cerebrovascular disease. The causes and mechanisms of atherosclerosis are still largely unknown. Serum levels of a lipoprotein, Lp(a), have been shown, in retrospective and some prospective clinical studies, to be associated with increased risk of myocardial and cerebral infarction. The active part of Lp(a), apo(a), has > 80% homology with plasminogen; thus it may competitively inhibit the thrombolytic action of plasminogen and enhance thrombogenesis. Lp(a) has been shown to be deposited in the vascular wall of the aorta and coronary vessels, but its presence in the cerebral vessels has not yet been shown. Autopsy specimens of vessels of the circle of Willis from 23 patients were examined for degree of atherosclerosis and deposition of apo(a) by immunohistochemistry with apo(a)-specific monoclonal antibodies. The amount of apo(a) deposition in cerebral vessels correlated well with the degree of cerebral atherosclerosis. Arterial deposition of apo(a) was found entirely within the endothelial cell and subendothelial cell layers. There was no staining within the media and adventitia, with the exception of staining within the endothelial cells of the vasa vasorum. Correlation between the morphology of apo(a) deposition and plaque stage was found suggesting that detection of apo(a) in endothelial cells is an early event in the development of the atherosclerotic plaque of cerebral vessels.
