A concept of equivalent-volume concordance coefficient for comparing target volumes in radiotherapy.
Article in Journal of applied clinical medical physics, 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
backgroundThe significant limitation of simple volume analyses for target volumes is that they disregard the spatial distribution of non-overlapping volumes and the surrounding dose gradient. PURPOSE: To present a concept of equivalent-volume concordance coefficient (CC
methodsBy using uniform expansion and Boolean operations, the non-overlapped volumes were segmented by a certain spatial distance (d) from the margin of V
resultsThe DVH could be divided into prescription dose region, rapid fall-off region, slow fall-off region and low-dose region according to dose gradients of 20 plans. The volume of V
conclusionsA reference penalty distance of 1 cm and a distance-penalty parameter of 1 are recommended for CC
