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

In our transient expression assays, the IE180 and TK promoters were markedly suppressed by the EP0 of the pseudorabies virus strains Ea and Fa (EP0/Ea, EP0/Fa). This is in contrast with the transactivating activity of EP0 from strain YS-81 (EP0/YS-81) in previous studies. Amino acid sequence alignment revealed several mutations in both EP0/Ea and EP0/Fa compared with EP0/YS-81. Most remarkable is a two-amino acid substitution next to the RING finger domain which was considered to be important for the transactivating activity of EP0 in previous studies. To address the effect of the two-amino acid substitution on the function of EP0, reverse mutants of EP0/Ea and EP0/Fa were generated. The subsequent expression assays indicated that this substitution was at least in part responsible for the effect on the regulatory activity of EP0. Our data suggested that EP0 may regulate the expression of the same genes in different pseudorabies virus strains differently.
