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

This study explored the effects of perfluorooctanoic acid (PFOA) on river sediment denitrification and its remediation using a coupled sulfur autotrophic denitrifying-Anammox microbial consortia. River sediments possessed intrinsic denitrification potential. However, PFOA did not inhibit ammonia nitrogen removal but accelerated nitrite oxidation, causing nitrate accumulation, altering the contents of extracellular polymeric substances and soluble microbial products, inhibiting heme-c secretion, and elevating nitrite reductase activity (0.22-0.93 ng nitrite/(min·mg protein)). After microbial enhancement, sediment PFOA tolerance and denitrification improved (initial ammonia removal rate was 0.247 mg/(g·day)), while heme-c secretion remained unaffected and nitrite reductase elevation showed PFOA concentration dependence. PFOA reduced the abundance of Proteobacteria and Sulfithrix in native sediments, whereas microbially enhanced communities exhibited higher stability. Enrichment of functional genes (hzsB, amoA) enhanced denitrification and stress resistance, providing insights and technical support for PFOA-contaminated sediment bioremediation.
