Changes in Pectoral Muscle Volume During Subacute Period after Radiation Therapy for Breast Cancer: A Retrospective up to 4-year Follow-up Study.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
Radiotherapy (RT) is an effective treatment for managing breast cancer patients with breast conserving surgery, but patients may experience radiation-induced shoulder problems. Even though the course of shoulder morbidity is unknown, pectoral muscle changes after radiotherapy can be a major cause of shoulder problems. Twenty-two patients treated with RT for unilateral breast cancer were included in the study. All patients underwent serial computed tomography (CT) imaging before and immediately after RT, as well as 2 months, 6 months, 2 years, and 3-4 years after RT. These CT scans were used to compare muscle volume changes. The pectoral muscle volume and muscle volume surrounding the scapular measurement was performed using 3D modelling after segmentation of the CT scans. In all patients, the pectoral muscle volume increased during the 2 months after RT, and there was continuous volume reduction from 2-48 months after RT. Changes in muscle volume ratio over time were analysed by repeated measure ANOVA and it was found that there was a significant change in the pectoral muscle volume (p < 0.001) from Just before RT and Immediately after RT at 2 month after RT. On the other hand, the changes in the muscle volume of the surrounding scapular were not significant.
