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

Complete ammonia-oxidizing (comammox) Nitrospira are recognized as key players in the nitrogen cycle, yet their ecological roles in extreme environments remain poorly understood. Here, we show that comammox Nitrospira occupy distinct ecological niches in Tibetan Plateau thermokarst lakes (pH 7.5-10.2) using stable isotope probing, metagenomics, and metatranscriptomics. While gross nitrification rates are significantly higher in subalkaline lakes due to the active presence of ammonia-oxidizing archaea (AOA) and bacteria (AOB), these canonical nitrifiers are inhibited under elevated pH. In contrast, comammox Nitrospira activity is significantly higher in alkaline than in subalkaline lakes, becoming the predominant nitrifiers with activities exceeding those of AOA and AOB by over 6- and 15-fold, respectively. This niche transition, coupled with the inherently low N
