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

Introduction: Forest management practices can alter canopy light environments and competitive intensities, thereby reshaping leaf functional traits and photosynthetic physiology. However, how different management modes coordinate leaf morphology, carbon gain, water use, and nitrogen utilization in coniferous plantations remains unclear. Methods: A field experiment was conducted in a Results: All modes significantly decreased leaf water content (LWC), with the largest reduction (8.44%) under SM. Only SM significantly reduced specific leaf area (SLA) by 27.3%. Net photosynthetic rate (Pn), stomatal conductance (Gs), and transpiration rate (Tr) were significantly increased by management, particularly under SM and RM. RM achieved the highest Pn (+59% vs. CK), whereas SM increased Gs and Tr the most (2.38 and 2.07 times CK). All treatments decreased instantaneous water use efficiency (WUE) and stomatal limitation (Ls). SM and RM significantly increased total nitrogen (TN) but decreased C/N. Contrasting nitrogen-use patterns emerged: SM increased leaf nitrogen content per unit area (Na) to 1.55 times CK and elevated δ¹ Discussion: Different forest management modes exhibited contrasting nitrogen-use patterns and altered the carbon-water trade-off. RM achieved the highest photosynthetic rate and PNUE while avoiding excessive nitrogen accumulation, thereby appearing to strike a better balance between carbon gain and nitrogen economy. Therefore, RM appears promising for enhancing carbon fixation and nitrogen use efficiency in
