Identification of 3 distinct HIV-1 founding strains responsible for expanding epidemic among men who have sex with men in 9 Chinese cities.

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
objectivesTo investigate the epidemiological relationships between HIV-1 strains that are spread among the men who have sex with men (MSM) populations of 9 cities across China and to analyze the origins and divergence times of the major epidemic strains found in the MSM population.
methodsA total of 583 HIV-1-positive subjects were recruited from high-risk MSM populations in 9 cities across China between 2009 and 2011. Nucleotide sequences of 1.0-kb pro-RT regions were amplified and sequenced. Phylogenetic and Bayesian molecular clock analyses were performed.
resultsThe overall distribution of HIV-1 genotypes was as follows: CRF01_AE, 62.1%; CRF07_BC, 18.2%; subtype B (United States-European), 15.9%; subtype B', 0.7%; other recombinants, 3.1%. In addition to the 2 distinct CRF01_AE clusters [cluster 1 (n = 157, 26.9%) and cluster 2 (n = 196, 33.6%)] previously reported by our group, we identified a novel CRF07_BC cluster (cluster 3) (n = 94, 16.1%) unique to China's MSM population whose strains were homologous and could be detected in all 9 cities. These 3 lineages of HIV-1 strains (clusters 1-3) accounted for 76.7% (447 of 583) of infections among MSM in China as a whole. Clusters 1, 2, and 3 were estimated to have been introduced into the MSM population in 1999, 2001, and 2001, respectively, indicating that the newly identified CRF07_BC cluster 3 is not a young lineage. However, it spread quickly in recent years.
conclusionsWe identified 3 distinct HIV-1 lineages (clusters 1-3) responsible for the recent upsurge of the AIDS epidemic among MSM in China. These 3 HIV-1 variants are spread widely among MSM throughout China, demonstrating remarkable founding effects.
