Optimizing energy consumption in radiotherapy: standard vs. hypo-/ultra-hypofractionation and becoming SMART (specific, measurable, achievable in radiotherapy).

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
purposeThe healthcare sector is a large greenhouse gas producer. Especially in radiotherapy (RT), a lot of electricity is consumed by the medical linear accelerator (linac) and associated patient travel. Our aim was to ascertain by how much electrical energy consumption and patient travel can be reduced by replacing normofractionated (NF) with emerging moderately hypofractionated (UF) or ultra-hypofractionated (UHF) concepts.
methodsWe connected an energy meter to our linac (VersaHD, Elekta©, Stockholm, Sweden) and evaluated different fractionation concepts (NF, HF, UHF) for 30 patients with target volumes of the prostate, breast, and spine. In addition to the energy measurements, we also conducted an analysis of the carbon dioxide (CO
resultsThis study measured the energy consumption of a linac (in kWh) and its impact on CO
conclusionThe adoption of HF and UHF treatment concepts can significantly reduce energy consumption and CO
