Next-Generation Sequencing Analysis for HIV-1 Genotyping and Drug Resistance Mutations Mapping in Sicily, Italy.
Article in Viruses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe advent and continuous improvement in antiretroviral therapy (ART) have profoundly altered the clinical course of HIV infection, shifting the focus from AIDS-related complications to the management of age-related comorbidities and non-AIDS-related hospitalizations. In this evolving context, optimizing ART is essential, with genotypic resistance testing (GRT), particularly through next-generation sequencing (NGS), playing a pivotal role.
methodsThis multicenter, retrospective cross-sectional study investigated HIV-1 subtypes, resistance mutations, and drug resistance profiles among 367 people living with HIV (PLWH) in Sicily, based on 384 GRTs performed at the Microbiology Laboratory of the University Hospital of Palermo.
resultsSubtype B was the most prevalent (50%), followed by circulating recombinant forms (30%). Among treatment-naïve individuals, resistance-associated mutations were infrequent, with prevalence rates of 0.4% for NRTIs, 5.5% for NNRTIs, 1.3% for PIs, and 0.8% for INIs. Conversely, treatment-experienced individuals showed significantly higher resistance rates, especially to NRTIs (16.3%), NNRTIs (10.6%), and INIs (9.6%). No significant differences in resistance patterns were observed between B and non-B subtypes.
conclusionsThis study provides the first regional overview of HIV drug resistance across Sicily. Despite the detection of resistance-associated mutations, the overall prevalence of clinically relevant resistance, particularly to currently recommended therapies, remains low, especially among treatment-naïve individuals.
