Molecular Transmission Dynamics of HIV-1 in Migrant Populations: Transmission Clusters and Demographic Diversity in Hangzhou, a Key Migration Hub in Eastern China.

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
objectivePopulation mobility complicates the prevention and control of HIV. To address these challenges, this study explored the molecular epidemiology of HIV among migrant populations in Hangzhou.
methodsPeople newly diagnosed with HIV/AIDS from 2020 to 2023 were divided into permanent migrant population (PMP), temporary migrant population (TMP), and non-migrant population (NMP). HIV-1
resultsPMP comprised people living with HIV in Hangzhou, characterized by younger age, higher education, and predominantly homosexual transmission. This population forms multiple large molecular clusters together with NMP. TMP accounted for the highest proportion of females and people infected through heterosexual contact, but the education level was the lowest. NMP had the fewest people living with HIV. The main subtypes identified were CRF01_AE, CRF07_BC, CRF08_BC and CRF55_01B. Drug resistance prevalence did not differ significantly among the populations. The molecular transmission network included 833 cases forming 275 clusters, with an overall sample inclusion rate of 23.04%. PMP, TMP and NMP inclusion rates were 27.10%, 19.03% and 21.4%, respectively. All molecular clusters involved migrant populations. Factors associated with inclusion in the network for migrants included current residence, household registration, STD history, sample source, and stage at diagnosis.
conclusionsMigrant populations play a major role in ongoing HIV transmission. Prevention and control measures should be strengthened according to population-specific characteristics. Molecular transmission networks are useful tools for assisting precise control.
