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

Postoperative adhesions frequently occur following abdominal surgical interventions, leading to serious morbidities and requiring new therapeutic strategies. The development of new therapeutic agents to reduce postoperative adhesions needs animal models that closely mirror human pathophysiology. In this study, we established a novel surgical adhesion model in cynomolgus monkeys, which are characteristically similar to humans. Our model reliably and reproducibly developed adhesions. Histopathological analyses revealed that monkeys undergoing our novel surgery method exhibited changes consistent with those in monkeys that underwent open abdominal surgery. Furthermore, the cellular components of the adhesion tissue in our monkey model reflected those reported in human adhesion tissue. Furthermore, time-course transcriptomic analyses showed that our model accurately recapitulates the well-known progression cascade of postoperative adhesions. In addition, it identified the upregulation of gene that is absent in rodents. We expect our novel surgical method to be a promising tool for elucidating the detailed biology of postoperative adhesions and for assessing new therapeutic treatments with high translatability to human biology.
