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

objectivesTo quantitatively analyze setup errors of 4 immobilization devices in precision radiotherapy for prostate cancer, their accuracy differences, and the factors affecting their setup precisions.

methodsWe conducted a retrospective analysis of 240 prostate cancer patients undergoing image-guided radiotherapy at Sun Yat-sen University Cancer Center from May, 2016 to May, 2024. According to the immobilization devices used, the patients were divided into 1.2 m vacuum bag group (

resultsThe setup errors differed significantly among the 4 groups in three-dimensional directions (

conclusionsThe customized prone board demonstrates clinically significant advantages for its high setup accuracies in RL and SI directions in spite of its systematic AP directional errors. The setup accuracy in the SI direction is especially important for patients with lymph node irradiation or low BMI. Our findings provide quantitative evidence for immobilization device selection and individualized optimization of precision radiotherapy for prostate cancer.
