Predictors of Duration of Transjugular Intrahepatic Portosystemic Shunt (TIPS) Procedure: A Retrospective Single-Center Study.
Article in Cureus, 2024. 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
purposeTo determine the relationship between clinical, procedural, hospital, and physician characteristics with the duration of the transjugular intrahepatic portosystemic shunt (TIPS) procedure.
methodsThis retrospective study included patients over 18 years of age who underwent an initial TIPS procedure between January 2005 and August 2020. Exclusion criteria were TIPS performed outside the institution and failed TIPS placement. A total of 154 records were included. Regression analyses were used to identify predictors of procedural duration.
resultsThe mean age at TIPS placement was 57 years. Seventy percent of patients were male and non-Hispanic whites (80.5%). The mean duration of the TIPS procedure was 169 minutes (SD: 78). Procedural duration was shorter when the etiology of cirrhosis was viral (mean: 144 min, SD: 84, p=0.008); the reason for TIPS was ascites (152, SD: 66, p=0.01); and the procedure did not require additional access (153 min, SD: 67, p=<.0001). The main clinical predictor of procedural duration was baseline bilirubin (Beta coefficient (β): 5.6 min, p=0.0007). In multivariable linear models, in those patients that did not require additional access, bilirubin (β: 4.9 min, p=0.005), etiology of cirrhosis, and physician experience were the main predictors of TIPS procedure duration. The effect of baseline bilirubin on procedural duration increased in the ascites group (β: 19.5 minutes, p=0.006), especially when additional access was not required.
conclusionsThe study demonstrates an association between baseline bilirubin, etiology of cirrhosis, and physician experience with the duration of the TIPS procedure. The mechanism underlying the positive association between baseline bilirubin and procedural time is possibly related to the degree of liver fibrosis.
