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 evaluates bioremediation using effective microorganisms (EM) to improve quality in the eutrophic Maricá Lagoon (RJ, Brazil). The intervention, implemented in late 2021, consisted of the regular application of EM in one of the lagoon's main fluvial contributors: the Mumbuca-Ubatiba drainage basin. To evaluate bioremediation, physicochemical and biogeochemical variables were monitored in the water column and sediments from 2020 to 2023. Whereas the drainage basin was sampled monthly, the lagoon was sampled every 3 months. Dissolved inorganic nitrogen (DIN) concentrations showed strong spatial variability in the system, reaching up to 2412 µM in the eastern margin (Mumbuca-Ubatiba)-dominated by ammonium (> 80% of DIN)-and up to 234 µM in the western margin (São Bento channel), where nitrate predominated (> 70%). Chlorophyll-a concentrations declined from 240 µg L⁻
