Culturable bacterial diversity and genome-encoded metabolic potential in Al Wahbah Crater's volcanic soils, Saudi Arabia.

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
The growing demand for sustainable biotechnological solutions has intensified interest in microorganisms inhabiting understudied and environmentally constrained ecosystems. Volcanic systems create ecological niches shaped by geochemical and physicochemical stressors, yet the culturable bacteria in many remain poorly characterized. Here, we investigated the culturable bacterial fraction in the soils of Al Wahbah Crater (Saudi Arabia), an underexplored volcanic ecosystem, and evaluated its members' hydrolytic enzyme production and the genome-encoded metabolic potential of the most-promising isolates. Using multiple media and incubation conditions, we isolated bacterial strains from three crater soil types, identifying 65 representative isolates through 16S rRNA gene sequencing. The culture collection was dominated by Bacillota, particularly
