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 compare the outcomes of chimney endovascular aneurysm repair (Ch-EVAR) and open surgical repair (OSR) for abdominal aortic aneurysm (AAA) in consideration of the lack of comparative evidence.

methodsThe subjects of this retrospective study were patients who underwent elective Ch-EVAR or OSR for short-neck AAAs between 2013 and 2020 at five vascular centers. The primary endpoint was 30-day mortality and the secondary endpoints were postoperative complications and midterm clinical outcomes, including renal function changes, reintervention, overall survival, and aneurysm-related mortality.

resultsWe analyzed 38 Ch-EVARs and 42 OSRs. The 30-day mortality rates were 2.6 and 2.4% in the Ch-EVAR and OSR groups, respectively (P = 1.00). The acute kidney injury incidence was higher in the OSR group than in the Ch-EVAR group (P < 0.01). The freedom from reintervention rate at 5 years was lower in the Ch-EVAR group than in the OSR group (81.0% vs. 100%, P = 0.04). Other midterm clinical outcomes did not differ between the groups.

conclusionsCh-EVAR may be a feasible treatment option for short-neck AAA; however, it should be limited to patients at high operative risk for OSR, considering the concern about its long-term durability.
