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

Microbes drive biogeochemical changes in ecosystems, including carbon (C) and nitrogen (N) cycling. Dam construction has altered riparian ecosystems worldwide, yet we know little about microbial community composition in riparian sediments and how it changes following dam removal and sediment/soil drainage. Here, we evaluate how riparian microbial communities change with increasing depth in the sediment profile for existing dams and over time following dam removal/breach and assess how various physico-chemical sediment properties influence microbial community composition. We studied microbial community structure for 12 riparian sites over a chronosequence of 0-234 years since dam breach. Sediment was collected every 0.3 m to a depth of 4 m. Aerobic taxa involved with N cycling (e.g., Nitrospirota) were dominant in surficial sediments, and increased in deeper sediments as time since dam breach increased. Anaerobic taxa implicated in C cycling (e.g., Bathyarchaeia, Anaerolineaceae) and iron reduction (e.g., Sva0485) were dominant in deeper, anoxic sediments, but declined the fastest post dam breach. These microbial trends provide insights into how riparian biogeochemical functions are impacted by dam inundation and the recovery and restoration of these ecosystems following dam removals.
