Impact of Radiation-Attenuating Drape on Exposure in a Contemporary Cardiac Catheterization Laboratory: The ATTENUATE Trial.
Article in Journal of the Society for Cardiovascular Angiography & Interventions, 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
Background: Despite recent improvements in radiation safety, interventionalists are increasingly exposed to radiation during cardiac catheterization laboratory (CCL) procedures. The RADPAD was designed as a protective scatter-radiation absorbing shield with early studies demonstrating a 20% to 62% reduction in scatter-radiation. The objective of this study was to examine the impact of the protective scatter-radiation absorbing shield in a large contemporary randomized controlled trial across multiple CCL procedures. Methods: The investigator-initiated, prospective, randomized, controlled ATTENUATE (rAdpad proTecTion drapE iN redUcing rAdiaTion Exposure) trial randomized CCL procedures 1:1 to use of the RADPAD vs no use of the RADPAD. The primary outcome of interest was the most proximal operator's dose area product (DAP)-normalized operator dose (E). Results: A total of 1000 CCL procedures were randomized 1:1 to use of the protective scatter-radiation absorbing shield (n = 500) vs no use (n = 500). The use of the protective scatter-radiation absorbing shield was associated with a 45.1% relative reduction in the DAP-normalized operator dose compared with no use of the protective scatter-radiation absorbing shield (0.64 vs 0.35 μSv/Gy⋅cm Conclusions: In the largest randomized controlled trial to date evaluating the RADPAD protective scatter-radiation absorbing shield, encompassing contemporary coronary and structural CCL procedures, use of the protective scatter-radiation absorbing shield led to a marked decrease in proximal operator radiation exposure when adjusted for the total radiation delivered during each procedure.
