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 evaluate the long-term outcomes of primary stent placement for hepatic artery kinks in liver transplant recipients.

methodsAfter institutional review board approval, all patients undergoing liver transplantation between February 2001 and February 2024 at a single institution who underwent primary stent placement were reviewed. Patients who had hepatic artery thrombosis or underwent balloon angioplasty alone were excluded. Patients who underwent stent placement for hepatic artery kink were included. Hepatic artery kinks were defined by an acute arterial bend with coaptation of the arterial wall which is typically due to redundancy of the transplant hepatic artery. Hepatic arterial patency was evaluated at 1, 3, and 5 years. Kaplan-Meier analysis was performed for primary patency.

resultsFifty-six patients underwent hepatic artery stent placement. Further stratification resulted in 15/56 patients undergoing stent placement for hepatic artery kink. Primary patency rates for hepatic artery kink patients (n = 15) at 1, 3, and 5 years were 92%, 92%, and 92%, respectively. Primary-assisted patency for stent placement for hepatic artery kink was 100% at 1, 3, and 5 years. One patient had mid-stent kinking which was categorized as a technical failure and required re-intervention (n = 1/15). No patients had kink propagation or arterial rupture.

conclusionIn conclusion, primary stent placement for hepatic artery kink has excellent long-term patency.
