Mid-to-long term outcomes following renal artery angioplasty in children and young adults with renal artery stenosis: a retrospective review.

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
backgroundThis study investigates the efficacy of renal artery angioplasty for pediatric renovascular hypertension (RVH) and describes the role of pre-procedural diagnostic imaging.
methodsClinical data of patients who underwent angioplasty for RVH from July 2014-May 2023 at a single, tertiary-care children's hospital were retrospectively analyzed. Renal angiography was performed in 74 children, mean age: 10.6 years (range, 3mos-20y). Mean follow-up: 2.5 years (range, 4d-10.4y). 45 angioplasty procedures were performed on 28 patients.
results11(39.3%) were cured (normotensive, no anti-hypertensive medications), 10(35.7%) were improved (improved BP, decreased anti-hypertensive dose or number of meds), and 7(25%) failed (no improvement) following 1st angioplasty. Of the 17 patients who improved/failed, 12 had a 2nd angioplasty procedure. Of those, 3(25%) were treated with cutting-balloons. 2(16.7%) were cured, 8(66.7%) improved, and 2(16.7%) failed. 5 patients underwent a 3rd angioplasty procedure. 4(80%) were treated with cutting-balloons. 3 (60%) of the 5 patients were cured, 2 (40%) improved. In all, 16/28(57.1%) of patients were cured, and 12/28(42.9%) improved. 19 patients with abnormal angiography had normal CTA(10), MRA(3), and US(17). 14 patients with normal angiography had abnormal CTA(4), MRA(2), and US(13). Major complication rate was 8.9%(4/45) and included renal artery stent with residual in-stent stenosis, arterial extravasation following cutting-balloon angioplasty, arterial dissection, and vasospasm, partially resolved with nitroglycerin/TPA.
conclusionsAngioplasty is an efficacious treatment for pediatric RVH, but may require more than one procedure to achieve successful clinical results. Angiography should be pursued when RVH is suspected, as other imaging modalities are commonly discordant with angiography.
