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

Rivers are hotspots of global methane emission and oxidation, yet research on aerobic methanotrophy in urban river sediments remains limited. Here, we collected sediments of the Jialing River and its tributary (Xixi River) from the urban area of Nanchong City (Sichuan Province, China), and used microcosm incubation and high-throughput sequencing methods to investigate the aerobic methane oxidation rate and the community structure of methanotrophs of these urban river sediments. Our results indicated that these urban river sediments exhibited substantial methane oxidation potential, with the maximum rate observed at the downstream site; high-throughput sequencing revealed that type I methanotrophs (Methylobacter, Methylomicrobium and Crenothrix) were the key microbial groups responsible for aerobic methane oxidation. The river physico-chemical properties such as dissolved organic carbon (DOC), total carbon (TC) and C/N ratio correlated significantly with aerobic methane oxidation rates. These findings suggest that urban rivers possess significant methane oxidation potential, which is notably affected by carbon and nitrogen contents. Future research should focus on the metabolic mechanisms of urbanisation on fluvial methanotrophy.
