Association between umbilical venous catheter‒related hepatic complications and tip position in neonates: a retrospective ultrasound-based analysis.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundUmbilical venous catheterization (UVC) is commonly performed in neonates, but improper catheter tip may lead to hepatic complications.
aimThis study aims to retrospectively analyze the relationship between UVC tip position and the occurrence of hepatic complications, utilizing ultrasound for early detection and characterization of hepatic injury.
methodsWe conducted a retrospective study of 206 preterm neonates who underwent UVC insertion in a NICU from January 2021 to December 2023. All patients with complete post‒UVC insertion abdominal ultrasound follow‒up records were included. According to the UVC tip position, neonates were divided into two groups: the Central Group and the Non-central Group. Within the non-central group, cases with the tip located in the ductus venosus (DV) formed the DV Subgroup. The incidence of hepatic complications, including portal venous gas, portal vein thrombosis, and hepatic parenchymal injury, was compared across these groups.
resultsHepatic complications were observed in 23 neonates (11.2%, 23/206), including portal venous gas (6.3%), portal vein thrombosis (1.9%), and hepatic parenchymal injury (2.9%). Among these, 9 cases (39.1%) occurred in the Central Group, while 14 cases (60.9%) were in the Non-Central Group, with 8 of these (57.1%) belonging to the DV Subgroup. The Non-Central Group accounted for the majority of complications, including all cases of hepatic parenchymal injury, with a proportion involving the DV Subgroup. These findings suggest an elevated risk of complications associated with non-central catheter tip position.
conclusionNon-central catheter tip positions increase the risk of hepatic complications. Regular ultrasound follow-up is crucial for ensuring proper tip position and early complication detection.
