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

A 2.4 kb fragment of hCMV (Towne strain), containing the 5' end of the major immediate-early gene, has been cloned, sequenced, and used to construct a series of mammalian cell expression plasmids. The effects of regulatory regions present on this fragment were assessed using human glycoproteins as reporter molecules. We compared secreted levels of Factor VIII, t-PA, and HIV-1 envelope glycoproteins in cells transfected with plasmids in which intron A of the immediate-early gene was present or absent. Secretion of several glycoproteins was significantly higher when cells were transfected with intron A-containing plasmids. Mutation of three basepairs in the strong nuclear factor 1 (NF1) binding site in intron A led to reduced transient expression levels, but not to the level observed in the absence of intron A. Reduced expression from NF1 mutant plasmids was roughly correlated with reduced binding in vitro of NF1 proteins to a synthetic oligonucleotide containing the mutation. The evidence indicates that sequences in intron A positively regulate expression from the hCMV immediate-early enhancer/promoter in transformed monkey kidney cells.
