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

Introduction: Land fragmentation is a persistent feature of China's rural tenure system, yet its psychological ramifications remain underexplored. This study investigates the causal association between land fragmentation and depressive symptoms among rural households, drawing on the Social Determinants of Health framework. Methods: Using data from the 2022 China Land Economic Survey, we employ an instrumental variable approach based on agricultural machinery subsidies to address endogeneity. Results: We identify a robust positive impact of fragmentation on depressive symptoms. Mechanism analyses reveal that fragmentation exacerbates depression through three distinct pathways: increasing agricultural production costs, intensifying labor burdens leading to time poverty, and eroding risk coping capabilities by reducing crop insurance participation. Furthermore, land transfer acts as a crucial moderator that significantly attenuates these adverse mental health effects. Discussion: These findings underscore that land consolidation is not merely an economic imperative but a public health intervention. Policy efforts should integrate land tenure reform with targeted mental health support for vulnerable smallholders.
