Mutations in the 3'-PPT Lead to HIV-1 Replication without Integration.
Article in Journal of virology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 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
Integration of the reverse-transcribed genome is a critical step of the retroviral life cycle. Strand-transfer inhibitors (INSTIs) used for antiretroviral therapy inhibit integration but can lead to resistance mutations in the integrase gene, the enzyme involved in this reaction. A significant proportion of INSTI treatment failures, particularly those with second-generation INSTIs, show no mutation in the integrase gene. Here, we show that replication of a selected dolutegravir-resistant virus with mutations in the 3'-PPT (polypurine tract) was effective, although no integrated viral DNA was detected, due to the accumulation of unintegrated viral DNA present as 1-LTR circles. Our results show that mutation in the 3'-PPT leads to 1-LTR circles and not linear DNA as classically reported. In conclusion, our data provide a molecular basis to explain a new mechanism of resistance to INSTIs, without mutation of the integrase gene and highlights the importance of unintegrated viral DNA in HIV-1 replication.
