Effects of the simian virus 40 origin of replication on transcription from the human immunodeficiency virus type 1 promoter.
Article in Journal of virology, 1995. 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
Positive and negative effects of DNA replication on gene transcription have been documented in a variety of systems. We examined the effects of the simian virus 40 (SV40) origin of replication on transcription from the human immunodeficiency virus type 1 (HIV-1) promoter, using a transient expression assay in COS-1 cells. The basal activity and Tat transactivation of the HIV promoter were greatly stimulated by the SV40 origin of replication independent of its position relative to the long terminal repeat. These effects were abolished by mutational inactivation of the SV40 origin and were reduced by a DNA replication inhibitor. The magnitude of promoter activation exceeded the increment expected from the increase in template number resulting from DNA replication. The SV40 T-antigen-induced DNA replication augmented the generation of both processive and nonprocessive HIV long terminal repeat-directed transcripts, and Tat primarily enhanced the initiation of those transcripts that were destined to be efficiently elongated. Our data suggest that the HIV promoter displays greater transcriptional activity on replicative DNA templates. This property may influence the activity of integrated HIV provirus and its transition from latency to productive infection.
