1 · What the graph read from 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.

2 · The registry

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

Climate change imposes negative impacts on forest ecosystems through both abiotic stressors, such as drought, and biotic stressors, such as insect-induced defoliation. Chinese pine (Pinus tabulaeformis), a primary afforestation species in the northwest region of China, has recently faced increasing threats from drought and defoliation, leading to widespread mortality. This study investigates the combined effects of drought and defoliation on the growth and non-structural carbohydrate (NSC) dynamics of Chinese pine seedlings. A greenhouse-based manipulative experiment lasting 80 days was conducted, incorporating three watering treatments (100% field water-holding capacity, 30-40% field water-holding capacity, and no watering) and two defoliation treatments (defoliated and non-defoliated). Under moderate drought, seedlings exhibited increased concentrations of soluble sugars and starch in leaves and stems, demonstrating an active resistance to drought stress. However, under severe drought, NSC concentrations significantly decreased in all organs. Defoliation exacerbated the negative effects of drought, particularly impairing the NSC reserves in roots, thereby weakening the resilience of seedlings. The combination between drought and defoliation significantly altered the allocation patterns of soluble sugars and starch among roots, stems, and leaves in Chinese pine, highlighting the critical role of NSC in plant responses to environmental stressors. This study emphasizes the need to consider both drought and defoliation challenges simultaneously in ecological restoration practices to ensure the resilience of forest ecosystems.
