Development of a 3D-printed bra with an incorporated prosthesis for post-mastectomy women.

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
backgroundWomen who have undergone mastectomy and do not undergo reconstruction often face challenges with existing bras and prostheses. Mismatches between generic prostheses and individual mastectomy cases result in physical and mental discomfort, such as pain, sweating, asymmetry, and concerns about prosthesis movement. Existing solutions are limited in their ability to address these challenges effectively.
objectivesThis study aims to develop a workflow for designing and fabricating a lightweight post-mastectomy bra with an incorporated prosthesis to improve fit, symmetry, and comfort.
designWe developed a customization and fabrication workflow based on a three-dimensional (3D) scan and the manipulation of its geometry to achieve fit and symmetry. We leverage the 3D-printed spacer fabric technique to produce a lightweight, breathable structure.
methodsWe conducted mechanical tests to determine printing parameters and evaluate the compression properties of the prosthesis and the bra materials. Additionally, we conducted a wear test for 10 women who underwent a mastectomy. A personalized bra was printed for each, and their feedback on fit and comfort was collected weekly over a 3-week test period.
resultsThe printed bras were lightweight (150-250 g), breathable, and provided improved symmetry. The mechanical tests confirmed comparable softness to silicone prostheses at significantly lower weight. The user study results show that the custom bras offer several advantages, including reduced weight and improved symmetry, though some participants noted mild fit and texture issues.
conclusionIntegrating the prosthesis into a 3D-printed bra offers a promising personalized solution for post-mastectomy women. This approach enhances comfort, symmetry, and emotional well-being, however, further improvements need to be made to improve the material and tactility.
