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
backgroundFluoroscopy-guided medical procedures require medical personnel to wear lead aprons (typically 0.5-mm Pb), which weigh up to 7 kg and can cause significant occupational injuries. A novel robotic radiation-blocking system, Radiaction, reduces full-body scattered radiation by 92% for all Cath-lab staff.
objectivesThis study aimed to determine if lighter lead aprons, when combined with Radiaction, can provide protection comparable to the standard 0.5-mm Pb aprons.
methodsThree setups were tested: (1) 0.5-mm Pb apron without Radiaction (control), (2) 0.25-mm Pb apron with Radiaction, and (3) 0.125-mm Pb apron with Radiaction. Radiation attenuation was measured through analytic calculations, bench tests, and clinical prospective controlled evaluations in an electrophysiology laboratory.
resultsAccording to analytical calculations, radiation reduction was 98% for 0.5-mm Pb aprons, 98.5% for 0.25-mm Pb with Radiaction, and 97% for 0.125-mm Pb with Radiaction. Bench tests showed reductions of 97%, 98.9%, and 98%, respectively. Clinical evaluations showed reductions of 99.2% for ablation procedures (98.8% upper- and 99.6% lower body) and 97.1% reductions for cardiovascular implantable electronic devices (CIED) procedures (94.4% upper- and 99.7% lower body) with the 0.25-mm Pb apron and Radiaction. With the 0.125-mm Pb apron and Radiaction, reductions were 97.9% for ablations (97.4% upper- and 98.4% lower body) and 81.7% for CIED procedures (65% upper- and 98.5% lower body).
conclusionsThe 0.25-mm Pb apron with Radiaction appears to surpass the standard 0.5-mm Pb apron in radiation protection, while the 0.125-mm Pb apron with Radiaction offers comparable protection. This suggests that Radiaction enables significant apron weight reduction during electrophysiologic procedures without compromising safety and potentially reducing orthopedic injuries.
