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

purposeTo establish the normal ranges of the main portal vein (MPV), left portal vein (LPV), and right portal vein (RPV) diameters in children and adolescents using abdominal contrast-enhanced CT.

methodsWe retrospectively enrolled children and adolescents (under 19 years) who underwent abdominal contrast-enhanced CT examinations in our hospital between January 2018 and January 2024. Subjects with conditions potentially affecting the portal vein diameter were excluded. Subjects' gender and age were collected. The height, weight, and body surface area (BSA) were also collected if available. The diameter of MPV was measured at three points: porta hepatis, midpoint, and the confluence of the superior mesenteric vein and the splenic vein. The diameter of LPV and RPV were also measured. The correlations between age, height, weight, BSA, and portal vein diameters were analyzed.

resultsA total of 1231 individuals were included, comprising 722 boys and 509 girls, with a median age of 10 years. 189 individuals' height, weight, and BSA information were obtained. The normal ranges of MPV, LPV, and RPV, depending on different age, height, weight, and BSA groups, were established. The diameters of MPV, LPV, and RPV were all positively correlated with age, height, weight, and BSA (all P < 0.001).

conclusionsThis study establishes the normal reference ranges for MPV, LPV, and RPV diameters in children and adolescents based on contrast-enhanced CT scans, which will help the diagnosis and treatment of hepatobiliary diseases.
