Effects of free and liposome-encapsulated antibiotics on adherence of Pseudomonas aeruginosa to collagen type I.
Article in Antimicrobial agents and chemotherapy, 1995. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 adherence of 27 clinical Pseudomonas aeruginosa strains to collagen type I was investigated by using a solid-phase assay. The influence of free antibiotics (amikacin, gentamicin, piperacillin, bacitracin, and polymyxin B) and liposome-entrapped antibiotics (amikacin and polymyxin B) on bacterial attachment to collagen type I was examined. The greatest inhibitory effect was shown for free and liposomal amikacin, which decreased the attachment of 74 and 100% of tested strains, respectively. The mean percent attachment (+/- standard deviation) in the presence of free amikacin was 65.7% (+/- 12.0%) as measured by solid-phase assay. In the presence of liposomal amikacin, the attachment ranged from 17.3% (+/- 6.0%) to 42.1% (+/- 9.4%), depending on the antibiotic solvent. In contrast, polymyxin B, even at a subinhibitory concentration, enhanced attachment of all P. aeruginosa isolates to collagen. Liposomal polymyxin B displayed a protective effect only when the encapsulated drug was of a low concentration. Application of liposome-encapsulated amikacin may be advantageous in injured tissues in which extracellular matrix structures become exposed.
