Proton Therapy Patient Selection Methods and the Impact of COVID-19: A Cross-Sectional International Survey.
Article in Journal of medical radiation sciences, 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
introductionThe COVID-19 outbreak has had far-reaching impacts on cancer services worldwide. It has yet to be described how the pandemic has impacted patient selection methods for proton therapy (PT) specifically. This survey aimed to investigate the current international methods implemented for PT patient selection and to determine whether COVID-19 has impacted PT practice.
methodsA 44-question survey was conducted from 29th January 2024 to 18th March 2024 using the Qualtrics platform. PT centres in 21 countries were invited to respond to the survey regarding patient selection methods used currently and prior to the pandemic, as well as impacts of COVID-19 on patient selection and service provision. The survey was disseminated with assistance from The Particle Therapy Co-operative Group.
resultsNine centres completed the survey: four in Europe, three in the United States of America (USA), and two in Asia. Diagnosis or indications lists, clinical trials group assignment, dose distribution, dose metrics, and expert recommendations were the most reported patient selection approaches within the last five years. Only one centre in the USA reported changes to patient selection approaches during the height of the pandemic, mainly ceasing use of clinical trial group assignment. Six of the nine centres continued to treat patients infected with COVID-19. Five respondents indicated various suspensions or delays for certain treatment groups.
conclusionsThe findings show most respondents did not alter their patient selection approaches during the pandemic. These findings, however, cannot be generalised to all PT centres due to the small sample size of respondents.
