Predictors of quality of life in individuals with non-traumatic unilateral transtibial amputation.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeQuality of life is a crucial outcome in evaluating adjustment to prostheses for individuals with non-traumatic lower limb amputation (LLA). This study aimed to identify prostheses-related factors that predict the quality of life in people with non-traumatic, unilateral, transtibial amputation. MATERIALS AND
methodsThis cross-sectional study surveyed 168 people who have experienced non-traumatic, unilateral, transtibial amputations and use prosthesis. They completed the 12-item short-form (SF-12) health survey and the comprehensive lower limb amputee socket survey (CLASS). We did correlation analyses to explore relationships between the variables and quality of life, followed by multiple regression analyses to assess their impact on quality of life outcomes.
resultsQuality of life had a strong positive association with comfort (r = 0.65, p = 0.001). There was a moderate positive association with socket stability (r = 0.46, p < 0.001) and suspension (r = 0.48, p = 0.001), as well as a weak positive association with appearance (r = 0.35, p = 0.001). In the final regression model, the comfort subscale of CLASS was the strongest predictor of quality of life (β = 0.51, p = 0.001).
conclusionThis study highlights that prosthesis socket comfort is the primary prosthesis-related factor predicting the quality of life for individuals with non-traumatic, unilateral, transtibial amputation. Thus, rehabilitation should prioritize modifiable factors, especially optimal socket fitting. Identifying user needs is essential for better prosthesis use, as enhancements in other prosthetic components do not necessarily improve quality of life without considering socket comfort.
