Prototype foamy virus integrase is promiscuous for target choice.
Article in Biochemical and biophysical research communications, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Retroviruses have two essential activities: reverse transcription and integration. The viral protein integrase (IN) covalently joins the viral cDNA genome to the host DNA. Prototype foamy virus (PFV) IN has become a model of retroviral intasome structure. However, this retroviral IN has not been well-characterized biochemically. Here we compare PFV IN to previously reported HIV-1 IN activities and discover significant differences. PFV IN is able to utilize the divalent cation calcium during strand transfer while HIV-1 IN is not. HIV-1 IN was shown to completely commit to a target DNA within 1 min, while PFV IN is not fully committed after 60 min. These results suggest that PFV IN is more promiscuous compared to HIV-1 IN in terms of divalent cation and target commitment.
