Sports facilities as substitutes for exercise-induced well-being: Evidence from four-wave CFPS panel data.
Article in PloS one, 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 relationship between sports participation and psychological well-being is well-documented, yet empirical evidence regarding the moderating role of community sports facilities remains inconclusive. This study tests whether facilities amplify or attenuate the well-being returns to exercise, using four-wave panel data from China (CFPS 2014, 2018, 2020, 2022).
methodsLinear regression models with individual fixed effects were constructed using China Family Panel Studies data (CFPS 2014, 2018, 2020, and 2022; the 2016 wave was excluded because its happiness item reached only 2.5% of adults). The analytical sample comprised 71,326 observations from 23,818 individuals. Self-rated happiness (0-10 scale) was regressed on binary exercise participation, community sports facility count (0-5+), and their interaction, controlling for age and log household income. Robustness was tested via instrumental variable estimation (community mean exercise rate) and propensity score matching.
resultsExercise positively predicted happiness (β = +0.074, p < 0.001) in the baseline fixed-effects model. The exercise × facility interaction was directionally consistent with the substitution hypothesis but not statistically significant (β = -0.022, p = 0.075). Marginal exercise effects declined from +0.095 in zero-facility communities (p < 0.001) to non-significance where three or more facility types were available. Instrumental variable estimation results (first-stage F = 3231.25; second-stage β = -0.158, p = 0.117). The IV estimate did not reach statistical significance, providing limited evidence on treatment effect heterogeneity. Four-wave balanced panel estimates confirmed the baseline finding (β = +0.074, p < 0.01). CES-D mediation accounted for only approximately 4.6% of the total effect.
conclusionsExercise benefits subjective well-being most where community sports facilities are least available-a directionally consistent substitution pattern. Facility investment may yield greater marginal returns when targeted at underserved communities.
