Effect of immobilization mask and beam energy on dose coverage to small joints in treating osteoarthritis with low-dose radiation therapy.
Article in Medical physics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeOsteoarthritis (OA) is the most common form of arthritis, affecting over 32 million Americans. Low dose radiation therapy (LDRT) is being used to treat OA, including small joints. Treatment energies recommended include both orthovoltage and 6 MV photons. This study evaluates treatment plan accuracy of small joints using a commercial treatment planning system (TPS) when 6 MV is used. The effect of bolus and immobilization mask on target dose coverage and the use of 2.5 MV beams are also studied.
methodsMonte Carlo calculated dose distributions were used to evaluate the dose calculation accuracy of small joints by the Varian Eclipse system (AAA V.16) for one patient. The CT based dose calculations with- and without an Aquaplast immobilization mask using 6 MV and 2.5 MV beams were compared. The target dose coverages were analyzed using a dose volume histogram (DVH). The effect of the Aquaplast mask on target dose coverage was evaluated. The doses calculated by Monte Carlo (MC) were regarded as the Gold Standard.
resultsThe dose calculated by the Eclipse system significantly underestimated D
conclusionEclipse calculations are less accurate, and underestimate D
