Distance to supermarkets and dietary variety among Japanese older adults: examining the moderating role of grocery delivery services.
Article in Public health nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
objectiveTo examine whether using grocery delivery services moderates the relationship between distance to supermarket and dietary variety among Japanese older adults.
designWe conducted a 1-year prospective cohort study. Distance to supermarket was measured using geographic information systems. We collected information on dietary variety score (range 0-10), regular use of grocery delivery services and socio-demographic factors using a questionnaire delivered via post.
settingThe current study was performed in Nada Ward, Kobe City, Japan, from 2017 to 2018.
participantsOlder adults living in Nada Ward (n 778).
resultsThe linear mixed model showed that a longer distance to supermarket (per 100 m: B = -0·07, 95 % CI -0·14, -0·01, P = 0·048) significantly predicted lower dietary variety after adjusting for socio-demographic factors. Using grocery delivery services (B = 0·28, 95 % CI -0·08, 0·64, P = 0·127) did not significantly predict dietary variety, and neither did its interaction with distance to supermarket (B = -0·04, 95 % CI -0·17, 0·10, P = 0·604).
conclusionsThe current study found that longer distance to supermarket was associated with lower dietary variety among Japanese older adults and that the use of grocery delivery services did not moderate this association. The findings imply that the use of grocery delivery services is insufficient to reduce the negative influence of inconvenient food access on dietary variety among older adults.
