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

introductionAbdominal wall surgery is emerging as a new subspecialty with reconstructive operations becoming increasingly complex. Central to any surgical subspecialty is comprehensive anatomical knowledge, which can be enhanced by cadaver dissection. An expert panel convened to develop a consensus framework highlighting key anatomical concepts and operative steps for teaching posterior component separation.

methodsThe panel consisted of opinion leading abdominal wall surgeons from the UK and Europe. Intellectual content derived from anatomy lectures, training videos, and cadaver dissection instructions formed the basis of the consensus framework. This framework was subsequently implemented during a pilot cadaveric workshop. Afterward, content from the workshop was further refined, resulting in this educational article, endorsed by all authors. This article comprises two sections, (1) theoretical aspects of abdominal wall anatomy; (2) stepwise technical guidance for cadaver dissection.

resultsIn the first section, "Essential Anatomy," we discuss: Anterior abdominal wall musculature, posterior abdominal wall, the semilunar line, preperitoneal space, subxiphoid anatomy and pelvic anatomy. In the second section, "Practical Anatomy taught via Cadaver Dissection," we discuss: Rives-Stoppa dissection, caudal extension, cranial extension, classic top-down transversus abdominis release and posterior component separation with Madrid modification (bottom-up or "Madrid PCS").

conclusionsUsing content delivered by senior members of the abdominal wall reconstruction community, this article provides a structured educational framework for teaching posterior component separation. This is intended as a reference guide for surgical training and details the essential anatomical and operative concepts every abdominal wall surgeon should know.
