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

This study investigates the role of water level fluctuations (WLF) in shaping phytoplankton community structure and gross primary productivity (GPP) in Hongfeng Reservoir, a karst reservoir in Southwest China, through long-term monitoring (2016-2023) across seven sampling sites. Results revealed substantial seasonal and interannual variations in water levels (maximum fluctuation range: 9.78 m) and nutrient concentrations, with total nitrogen (TN) and phosphorus (TP) peaking during wet seasons. Chlorophyta dominated species diversity (42-48%), while Cyanophyta exhibited the highest relative abundance. GPP fluctuated markedly between the dry (586.09 mg C/m²/d) and wet seasons (3018.66 mg C/m²/d), driven by phytoplankton abundance and community stability. The Bray-Curtis (BC) dissimilarity index declined over time, showing a negative correlation with WLF (r = -0.03) and a significant negative impact on GPP. WLF indirectly enhanced GPP by altering community dynamics. Findings highlight WLF as a critical regulator of phytoplankton structure and productivity, emphasizing the importance of hydrological management in mitigating algal blooms and balancing ecological stability. This study provides actionable insights for optimizing water level regulation to sustain reservoir ecosystem health in karst regions.
