The Effect of Stenting on Post-Stenotic Dilatation in Coarctation of The Aorta.

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.
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
The effect of stenting of native aortic coarctation (CoA) on post-stenotic dilatation (PSD) has not been previously described. We hypothesized that CoA stenting may lead to positive remodeling of PSD. Retrospective analysis of patients who underwent stent implantation for native CoA from 1999 to 2021 was performed. Primary outcome was incremental change PSD diameter and the PSD/DescAo (Descending Aorta) following stent implantation and comparison between covered and bare-metal stents. 90 consecutive patients, (26 female, average age at first intervention 12.0 years) were included. 35 patients (38.9%) underwent dilatation with bare-metal stents and 55 patients (61.1%) with covered stents. The covered stent subgroup was older (14.0 vs. 9.2 years old, p < 0.001) and PSD was larger (17.0 vs 14.0 mm, p < 0.001). Over a mean of 3.2 years, mean inter-catheterization growth of the PSD was blunted [- 0.05 mm, 95% CI (- 1.5 to 1.4)]. The covered stent subgroup demonstrated a negative inter-catheterization growth compared to the bare-metal stent subgroup (- 0.7 vs 1.6 mm, p < 0.001). When controlled for somatic growth, the PDS/DescAo decreased more significantly among those with covered stent vs bare metal (- 0.12 vs - 0.058, p = 0.004). Stenting of native CoA blunts the growth of PSD; covered stents were significantly associated with regression of the diameter of the PSD over time compared to bare-metal stents.
