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

purposeThe healthcare system contributes approximately 5% of global greenhouse gas emissions, yet the environmental impact of radiotherapy treatments remains inadequately assessed. MATERIAL AND

methodsWe selected all breast cancer patients (1959 patients) treated with adjuvant radiotherapy between 2015 and 2023 in one institution. We analyzed the CO

resultsOur study revealed a significant reduction in carbon emissions within the 5-fractions group compared to the 15-fractions group (26.69kg vs 57.13kg, p < 0.001), saving approximately the CO

conclusionMost of the carbon footprint of radiotherapy is due to travel. Hypofractionation could be an appropriate solution to protect the environment.
