1,9-Dimethyl-methylene Blue-Based Antimicrobial Photodynamic Inactivation: Sulfate-Reducing Bacteria Models Isolated from Oilfield Wastewater.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Sulfate-reducing bacteria (SRB) are responsible for biogenic acidification, which negatively impacts oil quality and presents significant economic and environmental challenges for the oil industry. The improper use of biocides often leads to the emergence of biocide-resistant SRB strains, posing additional risks of contaminating aquatic environments. This study aimed to evaluate antimicrobial photodynamic inactivation (API) as a control strategy for a consortium of biocide-resistant sulfate-reducing bacteria collected from an oil extraction field in the Recôncavo Baiano Basin, Brazil, under conditions representative of oilfield microbial communities. 1,9-Dimethyl-methylene blue (DMMB) was used as a photosensitizer at concentrations of 1.0, 1.5, and 2.0 μg/mL, activated by LED light (λ 630 ± 10 nm, CWContinuous wave, 125 mW) with energy densities of 8.0, 10.0, 12.0, 14.4, and 21.6 J/cm
