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

We have surveyed the tandemly repeated genes encoding U2 snRNA in a diverse panel of humans. We found only two polymorphisms within the U2 repeat unit: a SacI polymorphism (alleles SacI+ or SacI-) and a CT microsatellite polymorphism (alleles CT+ or CT-). Surprisingly, individual U2 tandem arrays are entirely SacI+ or SacI-, and entirely CT+ or CT-, although the SacI and CT alleles can occur in any combination. We also found that polymorphisms in the left and right junction regions flanking the tandem array fall into only two haplotypes (JL+ and JL-, JR+ and JR-). Most surprisingly, JL+ is always associated with JR+, and JL- with JR-. Thus individual U2 arrays do not exchange flanking markers, despite independent assortment and subsequent homogenization of the SacI and CT alleles within the U2 repeat units. We propose that the primary driving force for concerted evolution of the tandem U2 genes is intrachromosomal homogenization; interchromosomal genetic exchanges are much rarer, and reciprocal nonsister chromatid exchange apparently does not occur. Thus concerted evolution of the U2 tandem array occurs in situ along a chromosome lineage, and linkage disequilibrium between sequences flanking the U2 array may persist for long periods of time.
