Energy-specific attenuation and half-value layers of BaSO
Article in Annals of nuclear medicine, 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
objectiveWith the expanding use of lutetium-177 (Lu-177) radiopharmaceutical therapy, reducing occupational radiation exposure has become increasingly important. Conventional bedside shielding mainly relies on lead, which is heavy and difficult to handle. This study evaluated the gamma-ray shielding performance of lightweight and flexible barium sulfate (BaSO
methodsBaSO
resultsAttenuation of both the 113- and 208-keV photopeaks increased with increasing rubber thickness. Scatter radiation around 55 keV was almost completely eliminated by 5-8 mm of shielding. At a thickness of 5 mm, attenuation rates were 51.5% for the 113-keV photopeak and 21.5% for the 208-keV photopeak, increasing to 95.0% and 89.1%, respectively, at 51 mm. Exponential fitting yielded HVLs of 5.0 mm for the 113-keV photopeak and 14.7 mm for the 208-keV photopeak.
