Decreasing radiation exposure in interventional pediatric cardiology: a 10-year European single-center analysis of 3683 procedures.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo evaluate radiation exposure during pediatric cardiac catheterization over a 10-year period at a central European tertiary center and to establish contemporary, procedure-specific dose benchmarks and conversion factors for estimating effective dose (ED).
methodsAll cardiac catheterization procedures in patients < 18 years performed between 2015 and 2024 were retrospectively reviewed. For procedures with multiple components, cumulative dose area product (DAP) was proportionally allocated using weight-adjusted (DAP/BW) median values from single-intervention cases. ED was estimated in silico in randomly selected examinations using Monte Carlo simulation. Dose conversion factors between DAP and ED were derived. Additionally, a structured review of the literature on recently published data on radiation doses was performed.
resultsA total of 3683 procedures in 2494 patients (median age 3.8 years) were included. Body weight showed a stronger association with DAP than age. Median DAP/BW was 11.7 cGy·cm
conclusionRadiation exposure in contemporary pediatric cardiac catheterization is markedly lower than in earlier reports, with procedure complexity being the primary determinant of effective dose.
