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
Pollution by aromatic hydrocarbon compounds is closely associated with oil industry activities and poses significant environmental and human health risks. Biodegradation using hydrocarbon-degrading bacteria, particularly in combination with dispersants, offers a promising approach to mitigate such pollution. In this study, phenanthrene was used as a model compound to evaluate the effect of dispersant addition on the degradation capacity of Bacillus subtilis strain CYA27. Two dispersants were compared: a palm oil-based dispersant (Bio-OSD) and a petroleum-based dispersant (Non-Bio-OSD). The results showed that the presence of Bio-OSD and Non-Bio-OSD enhanced phenanthrene degradation, achieving up to 73.9% and 46.7% after 35 days, respectively. This improvement was attributed to increased substrate bioavailability, the potential use of dispersants as an auxiliary carbon source via a cometabolic mechanism, as supported by the detection of catechol dioxygenase activities (C12O and C23O) and selected metabolic intermediates, which provide preliminary evidence for possible enzymatic involvement in aromatic ring cleavage. Metabolic profiling using LC-MS/MS revealed that the degradation pathways utilised in the presence of dispersants included both the salicylic acid and phthalic acid pathways, which are further metabolised through the tricarboxylic acid (TCA) cycle. In contrast, phenanthrene biodegradation proceeded without a dispersant via the formation of 4-methoxy-1-naphthol, suggesting a methoxylation mechanism that potentially reduces toxicity but does not proceed to the TCA cycle. These findings revealed that dispersants not only enhance substrate bioavailability but also alter bacterial metabolic preferences, highlighting their dual role in oil spill bioremediation strategies. This work provides novel insight into phenanthrene catabolism and the mechanistic effects of dispersants on marine PAH biodegradation.
