Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Halophilic bacteria are remarkable microorganisms that excel in hypersaline environments. Their significant potential in various fields, such as industry and agriculture, positions them as vital players in advancing our technological and ecological efforts. In this study, three bacterial strains (QSLA1, QSLA2, and QSLA3) were successfully isolated from solar saltern ponds, attached to Qarun Lake, Fayoum governorate, Egypt, using nutrient agar (NA) culture medium derived from pond water. Morphological and physiological characterization revealed that these isolates are rod-shaped, gram-negative, catalase-positive, and motile. All isolates were identified as not spore-forming bacteria. The halo tolerance assay demonstrated that QSLA1 and QSLA2 are extremely halophilic, whereas QSLA3 is classified as moderately halophilic. Through 16S rRNA sequence analysis, it was determined that QSLA1 shares 91.26% similarity with Halomonas sp. RS-17, while QSLA2 exhibits 96.6% similarity with Halomonas sp. strain LR2-3. QSLA3 shows even greater similarity at 97.33% to Halomonas sp. GQ30. All isolates are capable of producing indole-3-acetic acid (IAA), but only QSLA2 has the ability to fix atmospheric nitrogen and solubilize insoluble phosphate. Additionally, QSLA1 demonstrates antifungal activity against Fusarium oxysporium f.sp. lycopersici in vitro under saline environment. Given these promising traits, we explored the potential of QSLA1 as a bio-control agent under greenhouse conditions at 1.5% salinity. These findings suggest that these bacterial strains could be used to develop sustainable agricultural practices, enhancing crop yields and reducing the reliance on chemical fertilizers and pesticides. Future applications of these strains could provide a valuable solution for improving agricultural productivity in saline environments.
