Genetic diversity and evolutionary analysis of HIV-1 among migration populations: a five-year cross-sectional molecular epidemiology study.
Article in Virus genes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
It is crucial to conduct strict surveillance on the diversity of HIV-1 to aid the generation of evidence-based biomedical and behavioral prevention programs to HIV/AIDS. In the current study, the social demographic characteristics, HIV-1 viral diversity among migration populations between 2017 and 2021 were investigated comprehensively and were compared with those in the previous five-year, between 2012 and 2016. Epidemiological investigation indicated that the male-to-female ratio decreased from 10.34:1 to 5.12:1, indicating significantly more female were infected when compared to the previous five years (p = 0.004). Moreover, an inversion on both the gender and nationality was found when comparison between study participants from southeastern ports and northwestern ports (p < 0.05) during the ten-year study period. Molecular epidemiology study revealed that two subtypes C/BC and CRF01_AE dominated, with the emerging of novel unique recombinant forms, including CRF01_AE/C/BC, CRF03_AB/C/BC, A/D, CRF01_AE/C, CRF08_BC/B, CRF01_AE/B, and B/CRF01_AE/C between 2017 and 2021. In addition, a significant higher proportion of drug-resistant viruses was found among this population when compared with the previous five-year (p < 0.001). In conclusion, the altered social demographic characteristics, co-circulation of CRF01_AE, C/BC recombinants, multiple URFs, and increasing amount of multiple drug-resistant viruses, indicated a new trend of the HIV-1 molecular epidemic in this population, which called for enhanced public health responses and prioritization of resources.
