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

backgroundWe previously established that neutrophils play a critical role in the development of experimental abdominal aortic aneurysm (AAA). The signal that initiates the influx of neutrophils to the aortic wall, however, remains unknown. In this study, we tested the hypothesis that complement participates in the development of AAA by providing the necessary chemotactic signal that recruits neutrophils to the aortic wall. METHODS AND

resultsUsing an elastase-induced model of AAA, we showed that pretreatment of C57BL/6 mice with cobra venom factor, which depleted serum of complement activity, protected mice from AAA development. Whereas control mice exhibited a mean aortic diameter of 156+/-2% on day 14 after elastase perfusion, mice treated with cobra venom factor exhibited a mean aortic diameter of 90+/-4% (P<0.001). Examination of mice deficient in factor B further indicated that the alternative pathway of complement played a major role in this process (mean aortic diameter of 105+/-4% in factor B-deficient mice, P<0.001 compared with controls). Activation of the alternative pathway led to generation of the anaphylatoxins C3a and C5a, which recruited neutrophils to the aortic wall. Moreover, antagonism of both C3a and C5a activity was required to block AAA, which suggests that each can independently promote the aneurysmal phenotype. In addition, we demonstrated that complement alternative-pathway involvement was not restricted to this experimental model but was also evident in human AAAs.

conclusionsThe identification of involvement of the complement system in the pathophysiology of AAA provides a new target for therapeutic intervention in this common disease.
