Recombinant characteristics of three novel HIV-1 second-generation recombinant forms composed of CRF01_AE and CRF07_BC isolated in Hebei province, 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
Human immunodeficiency virus 1 (HIV-1) is a fast-evolving, genetically diverse virus. The HIV-1 evolution rate is also significantly influenced by the frequency of HIV-1 spread in a population. Transmission via homosexual contact has become the predominant transmission route, leading to an increase in the HIV-1 epidemic in Hebei province, China. In this study, we report three novel HIV-1 CRF01_AE/CRF07_BC recombinant forms isolated from three men who have sex with men (MSM) in the cities of Shijiazhuang (20747) and Langfang (20809 and 20820). Phylogenetic analysis based on HIV-1 near-full-length genome (NFLG) sequences indicated that the three novel recombinant forms formed a distinct monophyletic branch that was separate from all known HIV-1 subtypes and circulating recombinant forms (CRFs). Breakpoint analysis showed that the three NFLGs displayed different recombinant patterns. NFLGs 20747 and 20809 had a recombinant pattern with subtype CRF01_AE gene fragments inserted into a CRF07_BC backbone, spanning from the gag to env gene regions, whereas NFLG 20820 had a recombinant pattern with subtype CRF07_BC gene fragments inserted into a CRF01_AE backbone. Subregion phylogenetic analysis confirmed that these three NFLGs comprised CRF01_AE and CRF07_BC. Our findings confirm the emergence of novel recombinant forms and highlight the need for continuous monitoring of the diversity of HIV-1 among sexually active populations, especially MSM, to better control the HIV-1 epidemic.
