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
objectivesThe current research aimed to study the biodegradation potential of biosurfactants isolated from marine bacteria against crude oil and heavy metals.
methodsHemolytic activity, oil displacement, drop collapse, tilted glass slide, and emulsification index tests were employed for screening the biosurfactant production efficiency of marine bacteria which was cultured on an enrichment mineral medium. Based on the highest emulsification activity, the most effective bacterial isolates were selected and subjected to biosurfactant isolation. Further, the characterization using TLC, FTIR, and LC-MS were performed. The bacteria and genes that produced biosurfactants have been identified via 16S rRNA sequence analysis.
resultsThe isolate MW 15 was selected for structural identification given its maximum oil displacement activity, effective surface tension reduction potential, and favourable emulsification index (E
conclusionTotally eight bacteria were isolated from petroleum hydrocarbon-contaminated marine harbour water. The isolate Stutzerimonas stutzeri showed better production of biosurfactants and biodegradation ability when compared with other biosurfactant-produced isolates. The current investigation promises the use of marine bacteria to produce biosurfactants with biodegradability, less toxicity, and eco-friendly nature.
