Efficacy of pelvic-abdominal shields in radiation protection of patients undergoing radial coronary angiography: experimental analysis and recommendations for radiology practice.
Article in Radiologia brasileira. 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
Objective: To develop and evaluate the use of radiation shields for patients undergoing coronary angiography via the radial approach. Materials and Methods: Two pelvic-abdominal shields were developed-one for the posterior region and one for the anterior region. To analyze the entrance dose and its attenuation through the patient until reaching a detector as residual radiation, two dosimeter strips (right and left) were created and inserted into a phantom. Results: Comparing the shielded and unshielded groups, we found that the radiation doses at all detector positions were significantly higher in the shielded group ( Conclusion: The use of pelvic-abdominal radiation shields made with 0.5 mm of lead is not recommended for patients undergoing interventional cardiology procedures, because it significantly increases radiation exposure and therefore does not comply with the As Low as Reasonably Achievable principle.
