Prevalence of drug resistance mutations in low-level viremia patients under antiretroviral therapy in Southwestern China: a cross-sectional study.

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
objectivesThis study aimed to evaluate the prevalence and characteristics of drug resistance mutations (DRMs) in patients with low-level viremia (LLV) in Southwestern China, as it has become a growing challenge in AIDS clinical practice.
methodsThis cross-sectional study was performed in Yunnan Province, Southwestern China. LLV was defined as 50-999 copies/mL of plasma viral load with antiretroviral therapy (ART) for at least 6 months. HIV-1 DRM detection used validated in-house protocol.
resultsA total of 470 sequences were obtained, and 13 HIV-1 genotypes were identified, among which CRF08_BC (47.5%), CRF07_BC (22.3%) and CRF01_AE (10.0%) subtypes were the most prevalent. The overall prevalence of DRMs was 45.7% (215/470), and the prevalence of DRMs to non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitors (PIs) was 39.4% (185/470), 20.6% (97/470) and 5.3% (25/470), respectively. The most common NNRTI-associated mutations were K103N (16.0%), E138A (6.6%), V179D (6.6%) and P225H (4.9%), and those in NRTIs were M184V (17.0%), D67N (3.4%) and K65R (3.0%). PI-associated mutations were infrequent, occurring in less than 1.8% of cases. The prevalence of NNRTI-associated mutations (K101E and Y188C) was found to be statistically significant among various LLV groups. Additionally, significant variations were observed in the prevalence of NNRTI-associated mutations (V106I, V106M, E138A and P225H), NRTI-associated mutation (K65R) and PI-associated mutations (L33F and Q58E) across different subtypes.
conclusionsThe prevalence of DRMs in ART-experienced patients with LLV was high, and HIV-1 genotypes exhibited diversity in Yunnan Province. These findings indicate that regular DRM monitoring during LLV episodes was essential for effective clinical treatment and management in this region.
