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 glycoprotein gp24 has been implicated in cell-cell adhesion of Dictyostelium discoideum. We have used a cDNA clone that codes for gp24 to screen cloned genomic fragments. Two closely linked genes (GP24A and GP24B) were recognized that generate mRNAs of about 650 base pairs after excision of a small intron and addition of poly(A). They appear to have arisen by tandem duplication of about 800 base pairs, followed by divergence. These genes are expressed within a few hours of the initiation of development; their mRNAs accumulate to a peak at 12 hr and persist until culmination. Both genes have short guanine-rich sequences (G boxes) upstream that have been shown to be involved in transcriptional regulation of other genes expressed during development of Dictyostelium. Their mRNAs code for proteins that are 85% identical. GP24A and GP24B mRNAs code for proteins with a hydrophobic domain followed by a highly charged carboxyl-terminal domain.
