Public transport use cessation and age-related functional decline: a quasi-causal analysis using the English longitudinal study of ageing.
Article in BMC public health, 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
backgroundMobility is crucial for older adults’ independence, health and wellbeing, and depends on access to suitable transport. As people age, they often stop using public transport, yet this cessation’s health consequences are poorly understood. A key challenge is bidirectionality: declining health both cause and result from cessation. To address this, a quasi-experimental approach was utilised, focussing on cessation caused by structural, non-health-related factors, aiming to quantify impacts on two major markers of ageing: gait speed and cognitive function.
methodsParticipants from waves 3–10 of the English Longitudinal Study of Ageing (ELSA) were classified according to their public transport use status, with ceasers further classified by cessation reason. Linear mixed-effects models were used to examine associations between public transport use cessation and health outcomes, testing for changes in the rate of decline following cessation, adjusting for age, sex, and relevant covariates.
resultsOut of 18,292 unique participants 3,400 ceased using public transport, 794 of them for structural reasons. Structural cessation was significantly associated with accelerated gait speed and cognitive declines (β=-0.001 m/s /year, p = 0.008; β=-0.012/year, p = 0.002 respectively), compared to pre-cessation. In contrast, health-related ceasers exhibited sharp declines at cessation, with insignificant subsequent changes in rate.
conclusionsPublic transport use cessation is a relatively common phenomenon, affecting almost a fifth of participants. While often caused by health-related reasons, cessation also independently leads to adverse health outcomes, specifically accelerated physical and cognitive declines. Policy for maintaining accessible and adequate public transport is essential for preserving mobility and might delay these declines.
