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

purposePreemptive thoracic endovascular aortic repair (TEVAR) has been used increasingly for uncomplicated type B aortic dissection (TBAD); however, its optimal indications remain controversial, particularly when the proximal landing zone involves the aortic arch. We evaluated the long-term outcomes of aortic arch preemptive TEVAR for uncomplicated TBAD.

methodsBetween July 2004 and January 2026, 473 patients with acute TBAD were treated at our institution and affiliated hospitals, 351 of whom completed initial medical therapy (follow-up, 1-241 months). Preemptive TEVAR was performed in 52 patients and 299 were managed medically. The subjects of this study were 41 patients who underwent preemptive TEVAR with a proximal landing zone in Zone 2 or 3. We compared the outcomes and aortic morphology on serial computed tomography (CT) of these 41 patients with those of 41 propensity-matched patients who did not undergo TEVAR.

resultsBefore matching, the TEVAR group had a higher prevalence of patent false lumen and a larger false lumen diameter. Freedom from aortic adverse events was higher in the TEVAR group during long-term follow-up, although the difference was not significant (P = 0.065). There were no aortic-related deaths after TEVAR, and CT demonstrated favorable aortic remodeling.

conclusionsAortic arch preemptive TEVAR was associated with favorable aortic remodeling and a trend toward improved long-term aortic outcomes.
