Objective and perceived neighbourhood walkability: population-average associations with transportation and recreational physical activity in urban-dwelling Canadian adults.
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
backgroundThe extent to which objective and perceived neighbourhood walkability together shape physical activity is not well understood. Using data from a national sample of urban-dwelling adults in Canada, our study examined whether perceived walkability moderated associations between objective walkability and physical activity undertaken for transportation (TPA) and recreation (RPA).
methodsNational data from 3,995 adults (Canadian Health Measures Survey; 2016-2019) including self-reported sociodemographic characteristics, perceived walkability, and TPA and RPA were linked to objective walkability scores from the 2016 Canadian Active Living Environments (Can-ALE) dataset. Pooled and sex-stratified covariate-adjusted Hurdle models estimated associations between objective and perceived walkability (main and interaction effects), used to determine population-average weekly minutes of TPA and RPA.
resultsObjective walkability was positively associated with TPA in the pooled (β = 9.39; 95% CI: 0.61 to 11.18) and sex-stratified samples (male β = 7.75; 95% CI: 5.42 to 10.08 and female β = 11.60; 95% CI: 8.88 to 14.31). Perceived walkability was positively associated with TPA in the pooled (β = 5.53; 95% CI:1.55 to 9.51) and male-only sample (β = 6.00; 95% CI: 0.31 to 11.68). Among males, perceived walkability was also associated with RPA (β = 8.13; 95% CI: 0.61 to 15.66). For males, the objective-by-perceived walkability interaction had a synergistic effect on TPA but an antagonistic effect on RPA. No interactions were observed among females.
conclusionsObjective and perceived walkability were positively associated with TPA. Perceived walkability was also linked to RPA among males. Their combined influence enhanced TPA but reduced RPA in males, suggesting physical and perceptual aspects of the neighbourhood built environment may interact differently across physical activity domains and sex.
