Effect of pipe material and disinfectant on active bacterial communities in drinking water and biofilms.
Article in Journal of applied microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
aimsWe investigated the combined effects of pipe materials and disinfection chemicals on bacterial community and its active RNA fraction in water and biofilms in a pilot-scale premise plumbing system. METHODS AND
resultsThe changes in bacterial communities were studied within four pipelines using copper and cross-linked polyethylene (PEX) pipe with chlorine or chloramine disinfection. The total and active bacterial communities and the presence of opportunistic pathogens (Legionella spp. and Mycobacterium spp.) were analyzed using 16S rRNA (gene) amplicon sequencing. The dominant classes were Alphaproteobacteria (31%) and Gammaproteobacteria (24%). Class Planctomycetia was increased in active fraction of chlorinated waters and PEX pipe biofilms and decreased in chloraminated waters and copper pipe biofilms. The alpha diversity of the active fractions in biofilms were highest in chloraminated PEX pipe samples (Chao1 mean = 163, p < 0.05, Kruskal-Wallis). Legionella spp. was more abundant and active in waters treated with chlorine than chloramine.
conclusionsDisinfectant had a stronger impact than pipe material on the bacterial community composition in water. A combined effect of pipe material and disinfectant was more evident on the composition and activity of the biofilm communities than the individual effect of copper, PEX, chlorine, or chloramine.
