1 · What the graph read from it

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.

2 · The registry

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

Transcripts for the Epstein-Barr virus (EBV) encoded nuclear antigens (EBNAs) are initiated at alternative promoters (Wp, Cp, for EBNA 1-6 transcripts and Qp, for EBNA 1 transcripts only) located in the BamHI W, C or Q fragment of the viral genome. To understand the host-cell dependent expression of EBNAs in EBV-associated tumors (lymphomas and carcinomas) and in vitro transformed cell lines, it is necessary to analyse the regulatory mechanisms governing the activity of the alternative promoters of EBNA transcripts. Such studies focused mainly on lymphoid cell lines carrying latent EBV genomes, due to the lack of EBV-associated carcinoma cell lines maintaining latent EBV genomes during cultivation in tissue culture. We took advantage of the unique nasopharyngeal carcinoma cell line, C666-1, harboring EBV genomes, and undertook a detailed analysis of CpG methylation patterns and in vivo protein-DNA interactions at the latency promoters Qp and Cp. We found that the active, unmethylated Qp was marked with strong footprints of cellular transcription factors and the viral protein EBNA 1. In contrast, we could not detect binding of relevant transcription factors to the methylated, silent Cp. We concluded that the epigenetic marks at Qp and Cp in C666-1 cells of epithelial origin resemble those of group I Burkitt's lymphoma cell lines.
