1 · What the graph read from it

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.

2 · The registry

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

Introduction: Following first clinical trials, the development of FLASH proton therapy (FLASH-PT) into a mature treatment modality is ongoing, while physical and biological conditions underlying the FLASH effect remain uncertain. Our aim is to assess the impact of these uncertainties on clinical FLASH-PT through a novel approach. Methods: A systematic literature review was conducted to collect relevant Results: In total, 14 preclinical and 27 treatment planning studies were identified. From these, 47 combined scores were reported in the impact assessment. A severe impact was found for patient selection in the context of radiobiological uncertainties for the robustness of the FLASH effect with respect to beam pauses and interruptions and for the evaluation of dose rate due to their importance in the treatment process combined with remaining unknowns. Moderate to insignificant impact was found for fractionation and FLASH-PT treatment delivery mode (transmission or Bragg peak beams), as these offer strategies to circumvent uncertainties. Overall, dose requirements, the use of multiple fields, and dose rate conditions emerged as the most crucial factors. Conclusions: Since uncertainties about the FLASH conditions hinder the utilization of its full pre-clinical potential in clinical practice, focusing future preclinical experiments to gain further phenomenological rather than only mechanistic insights on these aspects is recommended.
