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
Optimization of petroleum hydrocarbon degradation process in contaminated environments could be feasible using biosurfactant-producing bacteria. The aim of this study was to investigate crude oil degradation potential of biosurfactant-producing bacteria isolated from a marine ecosystem in Nigeria. Sediment and water samples were collected from ten marine locations in Nigeria, and physicochemical analyses were carried out on them. Isolates were identified and screened for biosurfactant production and crude oil degradation after 7 days of incubation. The screened isolates were assayed for biosurfactant production and crude oil degradation for 35 days and analysed every 7 days for changes in pH, OD and total petroleum hydrocarbon content. The strains with the highest yields were identified using PCR-based molecular method. Twenty bacterial species were isolated from the marine locations, and 15 of these isolates showed good potential for biosurfactant production and crude oil degradation. The isolates with the highest biosurfactant production using oil spread and emulsification index tests are
