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
backgroundResearch on the agronomic and seed production responses of maize to deficit drip-irrigation is limited in the arid region of northwest China. A two-year field experiment including multi-growth stage deficit drip irrigation treatments was conducted in a randomized block design to evaluate their effects on photosynthesis, resource use efficiency, grain yield, and seed quality of maize.
resultsResults indicated that a mild water deficit from emergence to the tasseling stage (EJ15) had no detrimental impact on plant growth, photosynthetic attributes, and yield components. Instead, it significantly increased chlorophyll contents (9.1-22.2%), leaf area index (5.1-19.3%), dry matter (6.7-24.5%), irrigation water productivity (13.5-14.6%), and grain protein (13.2-13.8%) compared to full irrigation at all growth stages (WCK) in 2023-2024. The EJ15 increased the grain yield (2.6-6.3%) compared to WCK, but the difference was statistically not significant. On the other hand, deficit irrigation during late vegetative or/and reproductive stage markedly decreased the photosynthetic parameters, resource use efficiency, and resulted in the lowest maize yield in both years.
conclusionMild deficit irrigation during the early vegetative stages of maize can be used as a water-saving strategy for enhancing growth, water use efficiency, and seed quality without compromising the final yield in the arid region of northwest China.
