A systematic review and meta-analysis: prevalence and clinical implications of anatomical variants of the hepatic portal vein.
Synthesis in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
The hepatic portal vein is the main vascular route responsible for collecting blood from the liver, spleen, pancreas, stomach, gallbladder, and intestines. Its key function is to metabolize the components acquired from the blood. The objective of this study was to analyze the characteristics of HPV variants and understand the possible clinical considerations that arise with them. The databases Medline, Scopus, Web of Science, Google Scholar, Cumulative Index to Nursing and Allied Health Literature and Latin American and Caribbean Literature in Health Sciences were researched until January 2024. Tree authors independently performed the search, study selection and data extraction. Methodological quality was evaluated with an assurance tool for anatomical studies. Pooled prevalence was estimated using a random effects model. A total of 31 studies met the established selection criteria. In this study, 21 articles were included for the meta-analysis with a total of 51,244 subjects. Of these 21 articles, the topics studied came mainly from Europe and Asia, with three (n = 554; 1.08%) and 11 articles (n = 50,090; 97.75%) respectively, also having six articles from North America (n = 442; 0.86%) and one from Africa (n = 158; 0.31%), discarding the articles from Oceania and South America. For the HPV trifurcation variant, it was 8% (CI = 7-10%). Apropos the right posterior portal vein variant, as the primary tributary from the main HPV, it was 7% (CI = 4-11%). About the right anterior portal vein variant originating from the left portal vein, it was 4% (CI = 1-6%). Finally, the prevalence of the isolated variants was 2% (CI = 1-3%). The knowledge of HPV and its anatomical variants is of utmost importance for both medical professionals and anatomists, as it is one of the vessels that collects blood from many important viscera found in the abdominal cavity, any structural alteration could be crucial in diagnosis and surgical procedures.
