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 portacaval space is a narrow space between the portal vein anteriorly and the inferior vena cava posteriorly. The contents of this space include normal structures such as the caudate lobe of the liver, part of the pancreas, normal lymph nodes, small vessels, fat, and the epiploic foramen. There are specific variants and pathologies localized to this space. This article navigates through the complex anatomy of the portacaval space, highlighting the surgical implications and CT and MR imaging appearances of pathologies that occur in or extend to the space, knowledge of which is crucial for guiding clinical management.
