Modeling and Validation of a Proton Therapy Couch Top.
Article in International journal of particle therapy, 2025. 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
Purpose: This paper describes the modeling of the kVue One Proton couch top (CQ Medical, Avondale, PA) for use in treatment planning system (TPS), and the verification of the calculated effect of the model in the TPS against measured radiological properties. Material and Methods: The kVue One Proton couch top consists of a higher-density shell surrounding a lower-density core. The radiological properties of the kVue One Proton couch top, as assessed by range pullback of direct and oblique incidence proton beams, were measured and used to evaluate different density overrides in a model of the couch top base created in the TPS, RayStation 12ASP1 (RaySearch Laboratories, Stockholm, Sweden). A similar approach was followed for MCsquare implementation. Results: The average value (of water equivalent thickness) for all water tank measurements in lateral and longitudinal positions in the uniform area of 2 protons kVue One Proton couch top (except the couch ramp) was 6.46 mm. The posterior HU profiles showed a ramp area more extended longitudinally than the 7 cm physical shape of the kVue One Proton Couch Top. This was confirmed with differences in WET measurements and HU profiles observed up to 14 cm inferiorly from the superior part of the couch top, the remaining area being uniform in WET. Conclusion: A 0.1 g/cm
