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

Nitrate ions constitute one of the major nitrogen resources for plant growth. However, the large amount of nitrate ions released into nearby waterbodies could cause eutrophication problems. This study developed a bio-based adsorbent from biowaste materials and functionalized it with amine groups through the Mannich reaction. The successful modification was confirmed using FTIR, SEM, and elemental analysis. Batch adsorption experiments were conducted under varying conditions, including contact time, pH, and initial nitrate concentration. Results showed that the amine-functionalized bio-adsorbent exhibited an enhanced capacity for nitrate removal, with a maximum adsorption capacity of 65.79 mg g
