1 · What the graph read from it

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.

2 · The registry

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

Purpose: This study examines how household age structure is associated with health-related expenditure in China, distinguishing broad medical and healthcare expenditure from narrower health/fitness expenditure. Methods: Using nationally representative China Household Finance Survey data from 2015, 2017, 2019, and 2021, we estimate associations between old-age and child dependency ratios and two expenditure outcomes and examine potential mechanisms through precautionary saving and household disposable income. Results: Old-age dependency is positively and relatively consistently associated with both broad medical and healthcare expenditure and narrow health/fitness expenditure. The association for child dependency is less stable across outcomes and specifications, but the mediation results are consistent with the possibility that household income constraints are relevant for discretionary health/fitness expenditure. Robustness, heterogeneity, and supplementary instrumental-variable analyses support an associational interpretation rather than a strong causal claim. Conclusion: Demographic structure is linked not only to the level of household health-related expenditure but also to its composition. Distinguishing old-age and child dependency helps clarify how demographic transition may shape household capacity for preventive and discretionary health investment.
