Characterization of the replication-competent porcine endogenous retrovirus class B molecular clone originated from Korean domestic pig.
Article in Virus genes, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Xenotransplantation from pigs offers an opportunity to resolve the shortage of human organs. The porcine endogenous retrovirus (PERV) cannot be eliminated because of its presence in the germline DNA. Three subgroups of the replication-competent PERV (PERV-A, PERV-B, and PERV-C) have been identified in pigs. We constructed a molecular clone of PERV-B from a Korean domestic pig BAC clone containing PERV genomes, and its replication competency was characterized in human cells. The pol region of PERV-B was detected in the genomic DNA of 293T cells transfected with PERV-B (465D1) and in the genomic DNA of 293T cells infected with PERV-B (465D1) viruses. The 293T cells transfected with PERV-B (465D1) were maintained for 140 days. PERV-B (465D1) showed the stationary replication competence with no toxicity in the cell growth.
