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

backgroundRight-sided aortic arch with Kommerell diverticulum (RAA-KD) has complex three-dimensional anatomy.

methodsWe retrospectively analyzed computed tomography angiography data from 65 adults with RAA-KD using centerline-based reconstruction. Patients were stratified by conventional maximal KD diameter (D

resultsAfter sex adjustment and false-discovery-rate correction, all aortic diameters increased with age; the ascending aorta, arch, and descending thoracic aorta also elongated, whereas aortic isthmus (L

conclusionsRAA-KD demonstrates generalized age-associated thoracic aortic enlargement and localized KD-associated remodeling. Comprehensive three-dimensional assessment may inform evaluation of the adjacent aorta and proximal sealing zone for thoracic endovascular aortic repair.
