Global and regional molecular epidemiology of HIV-1 among men who have sex with men: a systematic review and meta-analysis.
Synthesis in AIDS research and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesThe diversity of HIV-1 genotypes among Men who have sex with men (MSM) globally has changed considerably. The purpose of this study to assess the global prevalence of HIV-1 genotypes among MSM.
methodsPubMed, Embase, Scopus, and Web of Science were systematically searched to identify the articles. Pooled prevalence of HIV-1 genotypes was calculated and subgroup analyses were performed to examine the prevalence estimates across time and locations.
resultsA total of 95 studies were included in the final analysis, including 84,622 successfully genotyped samples. The predominant strains were CRF01_AE (34.46%), subtype B (31.16%), and CRF07_BC (24.72%). In subgroup analyses, Subtype B and C showed a declining trend over the years. However, CRF07_BC exhibited a consistent year-on-year increase, while CRF01_AE experienced a slight reduction after 2018. Notably, both subtypes currently account for more than 35% of the total. In addition, the distribution of HIV-1 subtypes in this population shown a clear regional distribution. Regionally, subtype B predominated in Latin America and Europe, CRF01_AE and CRF07_BC in Asia and China, while subtype C and CRF02_AG were dominant in Africa and the Middle East.
conclusionsGlobal and regions MSM HIV-1 subtypes are becoming more complex over time and the prevalence of recombinant viruses is increasing. Ongoing and effective surveillance of the global and regional molecular epidemiology of HIV-1 in MSM is critical for developing targeted preventive control measures against HIV.
