Comparison of the antimicrobial, anti-biofilm, and cytotoxic effects of thymol/ampicillin and thymol/cefotaxime against Escherichia coli bacteria.
Article in BMC research notes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveUsing essential oils in combination with antibiotics helps to combat antibiotic resistance. Thymol is a major phenolic compound found in many essential oils. The antimicrobial effects of thymol, ampicillin, cefotaxime, and their combinations were examined on Escherichia coli (E. coli) ATCC 25,922. Then, the antimicrobial effects of synergistic compounds were evaluated on twenty clinical strains. The chemical bonds, functional groups, and molecular interactions of the mentioned compounds were investigated with an FT-IR device. The time-killing curve, biofilm inhibition, hemolysis, and MTT methods were also conducted.
resultsAntimicrobial effects of thymol/ampicillin were greater than thymol/cefotaxime in both the ATCC and clinical strains. In the examination with the FT-IR device, both compounds showed a connection between components. The biofilm inhibition effect of thymol/ampicillin (62%) was greater than thymol/cefotaxime (39.28%). The bacterial killing time curve of Thymol/ampicillin was faster and more effective. The cytotoxic effects of compounds on red blood cells (RBCs) and human foreskin fibroblast (HFF) were lower than Triton X-100 (0.1%). In the treatment of diseases caused by E. coli bacteria, thymol/ampicillin had better effects than thymol/cefotaxime.
