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

objectivesThis study examined the relationship between rural/urban residency, household registration (hukou) status, and cognitive aging trajectories among older Chinese adults, aiming to understand how cumulative (dis)advantages across the life course contribute to differences in later-life cognitive health.

methodsWe used linear growth models to analyze 2011-2020 longitudinal data from the China Health and Retirement Longitudinal Study (N = 18,754) to assess associations of rural/urban residency and hukou status with level of cognitive function and age-associated cognitive changes. We further examined how age and method of urban hukou attainment were associated with cognitive aging trajectories.

resultsUrban residents with continuous urban hukou had the highest level of cognitive function and slowest age-related cognitive decline compared to all other groups. In contrast, rural residents with continuous rural hukou were the most disadvantaged. Rural-to-urban migrants enjoyed some urban advantages, but such advantages depended on whether they attained urban hukou, their age at urban hukou attainment, and the method of attaining urban hukou. DISCUSSION: These results support the cumulative (dis)advantages framework and demonstrate that institutional or policy discrimination such as through hukou policies plays a critical role in cognitive disparities among older adults. Taken together, the results suggest that reforms to provide greater resources to rural areas and access to urban hukou could be an important tool to improve cognitive health among rural and migrant populations, and ultimately reduce dementia in China.
