The Minimum Purchase Price policy in China and wheat production efficiency: a historical review, mechanisms of action, and policy implications.
Review in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
This study addresses challenges in China's staple grain production efficiency by examining the impact of the Minimum Purchase Price policy (MPP) on wheat production efficiency from the perspective of price support. First, relevant literature on price intervention policies is collected, summarized, and organized. This paper reviews previous research findings on the effects of the Minimum Purchase Price policy, social welfare implications, pricing studies, and comparative analyses of wheat production efficiency. Second, the study outlines the development of the Minimum Purchase Price policy and wheat production efficiency, and theoretically analyzes the mechanism by which the policy influences production efficiency. Finally, four recommendations for enhancing grain policy and improving wheat production efficiency in China are proposed: a focus on balanced macroeconomic development and coordinated efficiency, accelerating the allocation of production factors to unlock wheat production's potential, fostering a conducive external social environment for industrial integration, and optimizing the Minimum Purchase Price policy to maximize its benefits.
