Self-perceived muscular strength and its correlation with physical, mental, and emotional health status in long-term breast cancer survivors: a cross-sectional study.

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 aim of this study was to explore the association between different levels of self-perceived muscular strength and health status among long-term breast cancer survivors (LTBCSs), as well as to determine the factors that predict self-perceived muscular strength during this phase of long-term survivorship.
methodsA cross-sectional study was conducted with 80 LTBCSs, classified into three groups based on self-perceived muscular strength levels: very poor/poor (1-2), average (3), and good/very good (4-5). Variables analyzed, measured ≥ 5 years post-diagnosis, included other aspects of physical fitness, physical activity (PA) levels, pain, cancer-related fatigue (CRF), mood state, and health-related quality of life (HRQoL). ANOVA, Mann-Whitney U, and chi-square tests were performed, along with correlation and multiple regression analysis. Cohen's d was used to calculate effect sizes.
resultsAmong LTBCSs, 37.5% reported very poor/poor self-perceived muscular strength, 32.5% average, and 30% good/very good levels. Participants with lower self-perceived muscular strength exhibited declines in physical fitness, greater inactivity, higher pain levels, elevated CRF, mood disturbances, and reduced HRQoL (all p < 0.05). Regression analysis identified "general physical fitness" (β = 0.32; p = 0.01), "cardiorespiratory endurance" (β = 0.40; p < 0.01), "global health status" (β = 0.16; p = 0.04), and "breast symptoms" (β = - 0.16; p = 0.04) as significant predictors of higher self-perceived muscular strength (r
conclusionGood/very good levels of self-perceived muscular strength were observed in just 30% of LTBCSs. Those with lower self-perceived muscular strength exhibited more significant physical, mental, and emotional decline ≥ 5 years post-diagnosis. The combination of "general physical fitness," "cardiorespiratory endurance," "global health status," and "breast symptoms" accounts for 57.3% of the variance in self-perceived muscular strength levels among LTBCSs. IMPLICATIONS FOR CANCER SURVIVORS: Targeted interventions addressing self-perceived muscular strength could help mitigate long-term physical and emotional sequelae.
