An integrated assessment of water-energy-food benefits from small hydropower refurbishment in rural China.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Small hydropower, deeply embedded in rural China, plays an important role in poverty alleviation, energy transition, and rural development. However, the integrated benefits of refurbishment remain insufficiently understood. To address this issue, this study integrates the qualitative Gioia method, a game-theory-based weighted DEMATEL model, and a multi-attribute decision-making method based on Gray Pythagorean Fuzzy Hesitant Fuzzy Sets to construct a water-energy-food integrated benefit evaluation framework. The results show that small hydropower refurbishment forms a water-energy-food integrated benefit structure characterized by water as the nexus, energy as the medium, and food as the anchor. Benefits show clear functional differentiation, with management capacity improvement, ecological flow regulation, and irrigation coordination as driver benefits; social reputation and agricultural production stability as feedback benefits; while women's participation and greenhouse gas reduction represent peripheral benefits. Evaluation cases from five regionally representative plants show that geographical context, refurbishment design, and community infrastructure affect refurbishment benefits.
