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 recent discovery of a Cdelta encoding gene in artiodactyls has raised questions regarding the evolution of the gene. In the present study, we have analysed the complete rat Cdelta gene both at the cDNA and genomic levels, showing that the rat Cdelta gene is structurally similar to the corresponding mouse gene. Analysis of the rat immunoglobulin D heavy chain cDNA tail sequences, revealed two transcripts for the secreted form with varying sizes of their 3' untranslated region (UTR), resulting from usage of two different poly(A) addition signals. Furthermore, a membrane-bound form encoding transcript, possessing a long 3' UTR, was also observed. Phylogenetic analysis supports that the Cdelta gene appeared early in the evolution of vertebrates, and it was probably duplicated from the C micro gene more than 400 million years ago.
