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

The biological oxidation of ammonia, the first step of nitrification, is central to biological water purification processes for nitrogen removal. For drinking water treatment, particularly sourced from groundwater, low concentrations of available copper often limit the efficiency of nitrification. Copper dosing both enhances nitrification and affects the composition of the nitrifying microbial community. The mechanisms underlying the effect of copper on nitrifying community composition, ammonia oxidation, and subsequent nitrogen removal processes remain unknown. The objective of this study was to confirm the effects of copper availability on the relative abundance of complete (comammox) and canonical ammonia-oxidizing bacteria (AOB) in nitrifying communities within the drinking water treatment plant and to determine differences in their copper transport mechanisms. Comparative metagenomic analysis revealed that, unlike most AOB, many comammox
