Characterization of the HIV-1 molecular network in a middle-aged population aged 50 years and older in a City in Southern Sichuan, China.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study aimed to investigate the characteristics of the HIV-1 molecular network among newly diagnosed HIV-infected patients in southern Sichuan City. Plasma samples will be collected from eligible study subjects (n = 1249) during a cross-sectional survey conducted between 2016 and 2020. The HIV-1 polymerase (pol) gene sequences obtained from the collected samples will be used to perform phylogenetic analysis and characterize the genetic subtypes' molecular transmission networks. HIV-1 pol region sequences were successfully amplified in 898 cases, and seven genotypes were obtained, with CRF01_AE (331, 36.86%) and CRF07_BC (368, 40.98%) subtypes as the predominant prevalent strains in the region. 601 sequences entered the molecular transmission network. There were 302 highly connected individuals. Further multivariate analysis showed that the older the age (60-69 years, OR = 1.595, 95% CI: 1.026-2.479; ≥70 years, OR = 2.189, 95% CI: 1.295-3.699), RX and GJ counties (OR = 4.654, 95% CI: 2.776-7.803; OR = 6.847, 95% CI: 3.464-13.533) and CRF08_BC subtype (OR = 2.031, 95% CI: 1.225-3.367) were both more likely to be highly connected individuals. To effectively combat this local HIV-1 epidemic, HIV prevention and intervention programs should target older adults at least 60 years of age and registered residents in districts and counties within RX and GJ.
