Impact of preoperative triglyceride levels on hepatic encephalopathy development in TIPS patients: a retrospective cohort study.
Article in BMC gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundOvert hepatic encephalopathy (OHE) is a common complication following transjugular intrahepatic portosystemic shunt (TIPS) procedures in patients with cirrhosis. However, the relationship between preoperative triglyceride (TG) levels and post-TIPS OHE risk remains unclear. This study aimed to investigate whether elevated preoperative TG levels are independently associated with increased risk of developing OHE following TIPS in patients with cirrhosis.
methodsThis retrospective cohort study included 172 patients with cirrhosis who underwent TIPS at Yichang Central People's Hospital from January 2021 to December 2023. The primary exposure variable was preoperative TG level, and the primary outcome was the occurrence of OHE during follow-up. Cox proportional hazards regression models were used to analyze the relationship between TG levels and OHE risk, with stratified analyses conducted according to Child-Pugh classification and blood ammonia levels.
resultsThe incidence of OHE was significantly higher in the high TG group compared to the low TG group (45.2% vs 26.1%, P=0.026). After adjusting for multiple confounding factors, each 1 mmol/L increase in TG was associated with a 15.4% increase in OHE risk (HR=1.154, 95% CI: 1.042-1.426, P=0.036). Compared to the lowest quartile TG group, the highest quartile group showed a 26.5% increase in OHE risk (HR=1.265, 95% CI: 1.201-1.461, P=0.001). This association was more pronounced in patients with Child-Pugh class B/C.
conclusionsElevated preoperative TG levels are independently associated with increased risk of post-TIPS OHE development. Preoperative TG level assessment may help identify high-risk patients and facilitate the development of appropriate preventive strategies.
