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
Against the backdrop of the accelerating aging of the rural population, strengthening the construction of rural food circulation networks holds significant practical significance for improving the dietary quality of rural residents and narrowing the nutritional gap between urban and rural areas. From a food policy and economics perspective, this study investigates how market-based food environments moderate the nutritional consequences of demographic aging. Based on the food consumption survey data of 1,080 rural households in Shandong, Jiangxi and Gansu provinces in 2024, this paper empirically analyzes the influence mechanism of population aging (PA) and rural food markets (RFM) on the dietary quality of rural residents (DQRR) by used the linear regression model. The main research findings are as follows: (1) PA has a significant negative impact on the DQRR, while RFM can effectively promote the improvement of dietary quality for rural residents. This conclusion still holds true after a series of robustness tests. (2) RFM has a positive moderating effect on the negative impact of PA. (3) Food environmental perception, including supply sufficiency, spatial accessibility and economic affordability, is an important mechanism by which PA negatively affects DQRR. (4) Obtaining dietary nutrition information is an important mechanism for the food market to improve the quality of meals. (5) The impact of PA and RFM on the DQRR varies due to the gender of family dietary decision-makers, the strength of family clan networks, and the size of village populations. The new findings of this study help to understand the key influencing factors of the dietary quality of rural residents and provide a basis for food policy design aimed at responding to population aging and promoting the integrated development of urban and rural food markets.
