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

The class E genome of human cytomegalovirus (HCMV) contains long and short segments that invert due to recombination between flanking inverted repeats, causing the genome to isomerize into four distinct isomers. To determine if isomerization is important for HCMV replication, one copy of each repeat was deleted. The resulting virus replicated in cultured human fibroblasts with only a slight growth impairment. Restriction and Southern analyses confirmed that its genome is locked in the prototypic arrangement and unable to isomerize. We conclude that efficient replication of HCMV in fibroblasts does not require (i) the ability to undergo genome isomerization, (ii) genes that lie partially within the deleted repeats, or (iii) diploidy of genes that lie wholly within repeats. The simple genomic structure of this virus should facilitate studies of genome circularization, latency or persistence, and concatemer packaging as such studies are hindered by the complexities imposed by isomerization.
