Investigating the use of ionization chamber and solid-state detectors to evaluate kerma-area product meter accuracy under TG-125 geometry across variable field of views.
Article in Journal of applied clinical medical physics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundA kerma-area product (KAP) meter has been installed in a fluoroscopic system, and its accuracy has been evaluated in task group (TG)-190 geometry using an external detector. However, it is unclear that external detectors could evaluate the KAP meter accuracy under the TG-125 geometry. PURPOSE: This study investigated whether the reference air kerma rate (
methodsAn ionization chamber and three different SSDs (Radcal AGMS-DM+, Raysafe X2 R/F sensor, and RTI Dose Probe) were placed at the patient entrance reference point in a C-arm fluoroscopic system, and measurements were taken at FOV settings of 18, 25, 34, and 42 cm using both the TG-190 and TG-125 geometries.
