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

Previous to this work, typical genes were thought to move from one position to another infrequently. On the contrary, we now estimate that between one-fourth and three-fourths of the genes in Arabidopsis transposed in the Brassicales. We used the CoGe comparative genomics system to perform and visualize multiple orthologous chromosomal alignments. Using this tool, we found large differences between different categories of genes. Ten of the gene families examined, including genes in most transcription factor families, exhibited a median frequency of 5% transposed genes. In contrast, other gene families were composed largely of transposed genes: NB-LRR disease-resistance genes, genes encoding MADS-box and B3 transcription factors, and genes encoding F-box proteins. A unique method involving transposition-rich regions of genome allowed us to obtain an indirect estimate of the positional stability of the average gene. The observed differences between gene families raise important questions concerning the causes and consequences of gene transposition.
