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

The term Moynihan's hump or Caterpillar's hump is used to describe a "twisting" or "tortuous" right hepatic artery inside Calot's triangle. This abnormal artery passes in proximity to the gallbladder or cystic duct, posing a serious potential danger for surgeons operating on that area. In this case report, we present a patient who underwent a laparoscopic cholecystectomy due to gallstones within the gallbladder. During the surgical procedure, a tortuous right hepatic artery was identified within Calot's triangle, running adjacent to the gallbladder and cystic duct. Clipping and division of the short cystic artery allowed the artery to be mobilized safely, and the gallbladder was subsequently detached from the liver bed. The patient tolerated the whole procedure well, and his postoperative course was complication-free. Good anatomical knowledge is needed to identify the abnormality and prevent serious injury.
