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
Introduction: Increasing planting density and partial substitution of chemical fertilizer with organic fertilizer are important strategies for improving maize yield. However, how their interaction regulates dry matter accumulation, translocation, and grain-filling characteristics to affect yield formation remains unclear. Methods: A three-year field experiment (2023-2025) was conducted with three planting densities (70,000, 100,000, and 130,000 plants ha Results and discussion: The results showed that 17% organic fertilizer substitution improved radiation use efficiency at silking by 7.76%-20.42%. Although increasing planting density reduced per-plant dry matter accumulation by 20.29%-36.53%, 17% organic fertilizer substitution improved dry matter partitioning and partly alleviated the reductions in grain-filling duration and grain weight. Random forest analysis identified aboveground biomass accumulation as the primary predictor of yield and showed that maximum and mean grain-filling rates contributed more strongly to yield prediction than the active grain-filling period. Partial least squares path modeling further revealed that yield reduction under high density was mainly attributed to suppressed post-silking dry matter accumulation, while fertilization promoted dry matter accumulation and translocation, thereby strengthening their positive contributions to grain filling and yield formation. Across three growing seasons, 100,000 plants ha
