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

backgroundTreatment response in canine leishmaniosis is driven by the dog host, the Leishmania parasite, and pharmacological factors, with drug resistance increasingly undermining the effectiveness of therapy. Current methods for assessing antileishmanial drug resistance rely on culture-based approaches, which are slow and technically demanding. A direct quantitative PCR test (LeishGenR™) was applied to 104 clinical samples from 95 dogs in the Mediterranean area diagnosed with leishmaniosis in veterinary clinical settings and testing positive for Leishmania infantum by PCR. The assay enabled rapid detection of genetic drug-resistance biomarkers for allopurinol (metk), meglumine antimoniate (mrpa), and miltefosine (LdMT), providing a clinically relevant, timely alternative to culture-based approaches by directly analyzing circulating Leishmania infantum amastigotes.

resultsThe assay (LeishGenR™) showed high specificity (100%) and sensitivity (> 87.5%) for genetic drug-resistance profile assignment and a strong correlation with whole-genome sequencing for gene copy number assessment (metk: r = 0.878; mrpa: r = 0.943 and LdMT = 0.691). Genetic drug-resistance biomarkers were detected in 24.3% of L. infantum DNA from clinical samples analyzed (20/82; 95% CI 16.3-34.6), most commonly for allopurinol (13.4%; 95% CI 7.6-22.4), then meglumine antimoniate (9.4%; 95% CI 4.6-18.2), and for miltefosine (5.4%; 95% CI 1.8-14.8). Prevalence was higher in dogs previously treated for leishmaniosis.

conclusionThis study demonstrates the ability to detect genetic biomarkers of drug resistance in L. infantum directly from clinical samples of dogs with leishmaniosis. This method enables rapid, precise detection of genomic biomarkers, circumventing delays associated with culture-based methods and supporting more effective clinical management and surveillance. Among dogs with high parasitemia referred to clinics in Mediterranean regions sampled in this study, the findings reveal a significant prevalence of circulating L. infantum strains carrying genomic drug resistance biomarkers to standard treatments for canine leishmaniosis.
