Assessment of scatter radiation dose received by comforters and carers during digital breast tomosynthesis mammography.

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
introductionMammographic imaging can cause considerable stress and anxiety for some patients and may require someone to remain in the room during the procedure to provide both physical and emotional support. As such, these comforters and carers (C&C) are exposed to ionising radiation. Limited evidence is available stating the radiation dose received during a digital breast tomosynthesis (DBT) examination. This research aims to determine the optimal standing position for a C&C in the mammography room during a DBT mammogram that results in the lowest radiation dose, whilst providing high-quality imaging, care and comfort to the patient.
methodsA scatter detector was used to measure the dose at different standing positions of the carer relative to the patient during an examination. A polymethyl methacrylate (PMMA) phantom was also used to model the patient's breast and torso for further scatter dose measurements.
resultsThe median air kerma for craniocaudal views posterior to the patient is 0.75 μGy compared with 10.1 μGy to either side. The median air kerma for mediolateral oblique views for posterolateral position is 0.41 μGy compared with 2.6 μGy anterolateral. No significant effect from breast density is noted from the dataset.
conclusionThe optimal position for the C&C to stand is directly behind the patient in the craniocaudal position, and as far as possible posterolateral to the breast being imaged in the mediolateral oblique position. These two positions will result in the least radiation dose to the C&C.
