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

objectiveThe indication for preemptive thoracic endovascular aortic repair (TEVAR) is expanding due to improved outcomes in uncomplicated type B aortic dissection (TBAD) compared with best medical therapy (BMT). Long-term outcomes and future treatment strategies for TBAD managed with preemptive TEVAR will be reported. SUBJECTS AND

methodsOf 432 patients with acute TBAD treated at two centers between July 2004 and August 2024, 324 patients who completed acute BMT (1-237 months) were included. Their outcomes were compared with those of patients who did not undergo TEVAR.

resultsOf 324 patients, 277 (control group: CTR) continued BMT and 47 (Zone 2 landing n = 29, Zone 3 landing n = 7, others n = 11) underwent preemptive TEVAR. Propensity score matching was performed to compare the Zone 2 TEVAR group (Z2) with the CTR. There were more patients with patent false lumen in the Z2 (41% vs. 83%, p < 0.05). Pre- and post-TEVAR aortic diameters had decreased from 43.8 ± 6.8 mm to 40.2 ± 10.0 mm (p < 0.001) at 12 months, the same value as the CTR (40.2 ± 11.7 mm). The aortic event free rate (CTR vs. Z2, 1/5/10 years) was 76/69/69% vs. 100/96/96%, respectively, (p < 0.05). Although two patients (7.1%) had aortic events (enlargement of aneurysms) after TEVAR, no aorta-related deaths.

conclusionAmong patients who met the anatomic criteria, long-term outcomes of Zone 2 TEVAR performed during the subacute and early chronic phases were favorable. Preemptive TEVAR may be considered a viable treatment strategy for managing the aortic arch in the early stages of TBAD.
