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

purposeThis study aimed to evaluate the correlation between longitudinal changes in the sac size and proximal sealing length in patients who developed sac enlargement with type II endoleak (T2EL) after endovascular aneurysm repair (EVAR).

methodsThis retrospective, single-center study included patients who developed sac enlargement (≥ 5 mm increase) with T2EL after elective EVAR for an infrarenal abdominal aortic aneurysm between 2007 and 2023. The endpoints included the correlation between changes in the sac size and proximal sealing length, shortening of proximal sealing (decrease to a length of < 10 mm), secondary type Ⅰa endoleak (T1aEL), and aneurysm rupture.

resultsA total of 46 patients were included, with a median follow-up period of 6.2 years. A linear regression analysis demonstrated a moderate inverse correlation between changes in the sac size and the proximal sealing length. The cumulative incidences of shortening of proximal sealing and secondary T1aEL at 7 years were 24% and 10%, respectively, and a total of six (13%) patients required reintervention for secondary T1aEL. Two late AAA ruptures were observed. However, no aneurysm-related deaths occurred during the follow-up period.

conclusionsIn patients who develop sac enlargement with T2EL, proximal sealing length tends to decrease over time, which may contribute to secondary T1aEL after EVAR.
