Social Isolation and Daily Steps Are Associated With Fatigue in Older Women With Cardiovascular Disease: A Secondary Analysis of the MindMoves Trial.
Trial report in Journal of aging and physical activity, 2026. 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
BACKGROUND/
objectiveFatigue is a common cardiovascular disease (CVD) symptom in older women; however, contributing factors are unclear. This study examined the association of background characteristics, social isolation, movement behaviors, and serum biomarkers with fatigue in older women with CVD.
methodsThis cross-sectional study used baseline data from older women (≥65 years, N = 246) with CVD participating in the MindMoves trial. We examined background characteristics (age, race/ethnicity, education, marital status, body mass index, pain, and comorbidities), social isolation, movement behaviors (sedentary behavior, light physical activity, moderate-vigorous physical activity, daily step count, and cardiorespiratory fitness test), and serum biomarkers (brain-derived neurotrophic factor, vascular endothelial growth factor-A, and insulin-like growth factor-1). Fatigue was assessed using two items ("could not get going" or "felt everything was an effort") from the Center for Epidemiologic Studies-Depression scale. Two-sample t tests examined differences in background characteristics across subgroups with fatigue versus without, and logistic regression examined whether social isolation, movement behaviors, and serum biomarkers were associated with fatigue.
resultsFatigue was present in 17% of participants. A unit increase in social isolation score was associated with greater odds of fatigue (adjusted odds ratio = 2.38; 95% confidence interval [1.41, 3.99]), while an increase in walking steps by 1,000 per day was associated with lower odds of fatigue (adjusted odds ratio = 0.74; 95% confidence interval [0.59, 0.93]) in the fully adjusted models. Other factors were not associated with fatigue.
conclusionProspective studies are needed to investigate fatigue-related factors in diverse patients with CVD. Significance/Implication: Interventions involving walking and group exercise may mitigate fatigue in older women with CVD.
