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
To understand the mechanism of development of cross-resistance in food pathogen Bacillus cereus against an antimicrobial peptide pediocin and antibiotic alamethicin, the present study was designed. Pediococcus pentosaceus was taken as a source of pediocin, and it was purified by ammonium sulphate precipitation followed by cation exchange chromatography with 14.01-fold purity and 14.4 % recovery. B. cereus strains alamethicin-resistant strains (IC50 3.23 µg/ml) were selected from sensitive population with IC50 2.37 µg/ml. The development of resistance in B. cereus against alamethicin was associated with decrease in alamethicin-membrane interaction observed by in vitro assay. Resistant strain of B. cereus was found to harbour one additional general lipid as compared to sensitive strain, one amino group lacking phospholipid and one amino group containing phospholipid (ACP). In addition, ACP content was increased in resistant mutant (29.7 %) as compared to sensitive strain (14.56 %). The alamethicin-resistant mutant B. cereus also showed increased IC50 (58.8 AU/ml) for pediocin as compared to sensitive strain (IC50 47.8 AU/ml). Cross-resistance to pediocin and alamethicin in resistant mutant of B. cereus suggested a common mechanism of resistance. Therefore, this understanding could result in the development of peptide which will be effective against the resistant strains that share same mechanism of resistance.
