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

Reactivation of Epstein-Barr virus (EBV) from latency involves activation of the Zp promoter of the EBV BZLF1 gene. This occurs rapidly and efficiently in response to cross-linking the B-cell receptor on Akata Burkitt's lymphoma cells. After optimizing conditions for induction, signal transduction responses to B-cell receptor cross-linking were observed within 10 min, well before any autoactivation effects of BZLF1 protein. The primary events in reactivation were shown to involve dephosphorylation of the myocyte enhancer factor 2D (MEF-2D) transcription factor via the cyclosporin A-sensitive, calcium-mediated signaling pathway. This and other signal transduction events were correlated with the quantitative promoter analysis reported in the accompanying paper (U. K. Binné, W. Amon, and P. J. Farrell, this issue). Dephosphorylation of MEF-2D is known to be associated with histone acetylase recruitment, correlating with the histone acetylation at Zp during reactivation that we reported previously (Jenkins et al., J. Virol. 74:710-720, 2000). Histone deacetylation in response to phosphorylated MEF-2D can be mediated by class I or class II histone deacetylases (HDACs); HDAC 7 was the most readily detected class II HDAC in Akata and Raji cells, suggesting that it may be involved in Zp repression during latency.
