The Association of Race and Ethnicity with Six-Minute Walk Distance: The Multi-Ethnic Study of Atherosclerosis.
Article in Ethnicity & disease, 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: The limited data on functional capacity among older Americans suggest lower 6-min walk distance (6MWD) among African American than among White persons. We aimed to investigate the association of race and ethnicity with 6MWD while accounting for sociodemographic, behavioral, health care, and comorbid conditions. Methods: We performed a cross-sectional analysis of the Multi-Ethnic Study of Atherosclerosis cohort, composed of men and women ages 45-84 y who self-reported being African American, Chinese, Hispanic, or White, were free of clinically evident cardiovascular disease (CVD) between 2000 and 2002, and attended the sixth exam (2016-2018). 6MWD was obtained by participants walking at their own pace along a flat 20-m course under staff supervision. Linear regression models were utilized to adjust for age, sex, height, body mass index, site, education, income, private health insurance, health behaviors, health status, Kansas City Cardiomyopathy Questionnaire (KCCQ) score, CVD risk factors, and heart and lung function parameters. Results: Among 1829 participants (mean age, 73 y; age range, 59-96 y; 53% female; 24% African American; 14% Chinese; 21% Hispanic; 41% White), mean 6MWD was 33 to 56 m lower for non-White than for White participants. Differences in 6MWD narrowed after adjustment for covariates but remained significant for African American (-13 m; 95% confidence interval: -22, -3) compared with White participants. Conclusions: Among older adults who identified as White, Chinese, African American, or Hispanic, differences in 6MWD were smaller than what is considered clinically meaningful or not significantly different after consideration of socioeconomic status, health behaviors, comorbid conditions, cardiovascular parameters, and pulmonary function.
