Prevalence of antibiotic resistance gene in different wastewater treatment systems and effluent-irrigated soils through metagenomic analysis.

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.
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
Wastewater treatment systems (WWTS) are considered to be the main source of antibiotic resistance genes (ARGs) spreading into the environment. In this study, samples were collected from WWTS influent, biological treatment tank effluent, and recycled water treatment plant (RTP) effluent during summer and winter, followed by metagenomic sequencing. The study investigated the differences in antibiotic resistance gene transfer between two typical wastewater treatment plants (WWTPs) processes and the impact of recycled water irrigation on ARG dissemination in soil. The WWTS (HD and MD) adopting two combined processes of "Adsorption-Biodegradation Process(AB )+ Anaerobic-Anoxic-Oxic Process(AAO)" and "AAO + Membrane Bioreactor(MBR)" as the research objects for the first time.The primary ARGs types identified were multidrug resistance, tetracycline, macrolide, and aminoglycoside resistance genes. The top three ARGs subtypes by relative abundance in the influent, biological treatment tank effluent, and total effluent were msrE, mphE, and ANT(6)-Ia, respectively. Seasonal variations did not significantly influence the distribution of ARGs in the two WWTSs. The AAO and AB processes increase the relative abundance and diversity of ARGs, while ARGs relative abundance decreases after RTP treatment but may proliferate new ARGs subtypes. Additionally, the efficiency of reducing the relative abundance of ARGs in summer is higher than that in winter. The two WWTSs were able to efficiently remove msrE and mphE. The abundance and diversity of ARGs and microorganisms were maximum in soil samples from the RTP. The microbial genera significantly related to ARGs may become its potential host, such as Rhodanobacter had significant correlations with ropB2, carA, and oleB. These results provide new insights into the control of ARGs contamination and focus on the risks associated with irrigated wastewater.
