Longitudinal associations between physical activity and preferred walking speed in community-dwelling older adults: a 4-year follow-up study.
Article in European review of aging and physical activity : official journal of the European Group for Research into Elderly 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
backgroundThe ability to engage in physical activity reflects preserved physical function, autonomy, and well-being in older adults, making physical activity a key outcome of healthy aging. Walking is a common form of physical activity in later life, so understanding how walking speed is associated with overall activity is particularly important. This study examined 4‑year changes in physical activity energy expenditure (PAEE) in community‑dwelling older adults and assessed preferred walking speed in relation to PAEE.
methodsThis study used data from AGNES, a 4-year follow-up study of initially 75-, 80-, and 85-year-old adults. PA was measured using thigh-worn accelerometers and ECG monitors, with PAEE estimated using a branched equation model integrating heart rate and acceleration data. Preferred walking speed was measured using a self-paced six-minute walk test. Associations between PAEE, walking speed, and their 4-year changes were examined using linear mixed models.
resultsAmong 299 participants, PAEE declined by 16.9 kJ·kg
conclusionsIn community-dwelling older adults, PAEE declined substantially with age, more steeply than in total physical activity previously reported in similar cohorts. Walking speed was strongly associated with PAEE, but its change was not consistently associated with changes in PAEE.
