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

Reclaimed water with elevated nitrogen (N), phosphorus (P), and organics triggers eutrophication in replenished landscape waters. Conventional remediation methods face challenges of complexity and high costs. Filamentous algae ponds (FAPs) efficiently absorb N and P and produce harvestable biomass. Oedogonium is particularly adept at converting nutrients in reclaimed water into algal biomass. The effects of these cultivation conditions on Oedogonium sp. nutrient assimilation, photosynthetic parameters, and biomass recovery were evaluated with batch experiments using varying light-dark ratios (L: D ratios), nitrogen-phosphorus concentrations and their ratios (N/P mass ratios of 7, 14, 21, 28, and 35), and initial biomass loading. Specifically, Oedogonium sp. exhibits an optimal N/P mass ratio of 14. At a P concentration of 1 mg-P L
