Evidence for circulation of high-virulence HIV-1 subtype B variants in the United Kingdom.

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
The evolution of HIV-1 virulence has significant implications for epidemic control. Recent phylogenomic analyses identified low-prevalence HIV-1 variants exhibiting significant differences in disease progression. We analysed 40 888 partial HIV-1 pol sequences from the UK HIV Drug Resistance Database (UKRDB) across subtypes B, C, A1, and CRF02AG. We identified phylotypes with putative differences in transmission/phylogenetic patterns and assessed their virulence trends using pretreatment viral loads, CD4 cell counts, and four statistical methods. We classified three subtype B phylotypes-PT.B.40.UK, PT.B.69.UK, and PT.B.133.UK -as variants of interest (VOIs) due to significantly higher viral loads and/or accelerated CD4 decline. PT.B.40.UK and PT.B.69.UK exhibited higher viral loads, 4.93 log
