1 · What the graph read from it

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.

2 · The registry

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

backgroundStaphylococcus pseudintermedius is the main etiological agent of canine pyoderma and exhibits increasing multidrug resistance. Due to the reduced efficacy of antimicrobials, topical combinations of antimicrobial agents-such as chlorhexidine (CHX) and clotrimazole (CLT)-have gained attention as an alternative.

objectiveTo evaluate the in vitro antibacterial activity and pharmacological interaction of a 2:1 CHX-CLT combination against S. pseudintermedius isolates from canine pyoderma. MATERIALS AND

methodsSixteen isolates of S. pseudintermedius were obtained from canine pyoderma and identified by PCR detection of the nuc gene. Methicillin resistance was assessed both phenotypically, by oxacillin disk diffusion, and genotypically, through mecA detection. Minimum inhibitory concentrations for CHX, CLT and their 2:1 combination were determined by broth microdilution using resazurin. The fractional inhibitory concentration index was calculated to assess drug interaction.

resultsAll isolates carried both nuc and mecA genes, while only 25% were phenotypically resistant to oxacillin. CHX exhibited MIC

conclusionsThe CHX-CLT combination demonstrated enhanced in vitro antibacterial activity with predominantly additive interactions against S. pseudintermedius. The results support the rational use of CHX-CLT topical formulations as an effective therapeutic alternative for canine pyoderma in the context of growing antimicrobial resistance.
