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

Hepatic biliary injury is one of the most common complications in cholecystectomy and is frequently accompanied by arterial injuries. Because there are several anatomical variations of the hepatic ducts, including the accessory hepatic ducts (AHDs), it is important to consider not only the anatomical position of the hepatic ducts but also those of the AHDs in cholecystectomy. However, the topographical relationships between the AHDs and the hepatic arteries are still poorly understood. In the present study we show that AHDs were observed in 7 out of 59 (11.9%) of the cadavers. There was a single AHD in the 6 out of the 7 cadavers and double AHDs in one. In these cases, the right AHDs emerged from the anterior medial segment of the liver piercing the parenchyma, while the left AHDs emerged directly from the anterior part of the caudate lobe. The right AHDs ran anterior to the right hepatic artery, while the left AHDs ran posterior to the hepatic arteries. The topographical relationship between the AHD and the hepatic artery system was thus reversed in the cases of the right and the left AHDs.
