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

Ninety-nine members of the salmonid HpaI and AvaIII families of short interspersed repetitive elements (SINEs) were aligned and a general consensus sequence was deduced. The presence of 26 correlated changes in nucleotides (diagnostic nucleotides) from those in the consensus sequence allowed us to divide the members of the HpaI family into 12 subfamilies and those of the AvaIII family into two subfamilies. On the basis of the average sequence divergences and the phylogenetic distributions of the subfamilies, the relative antiquity of the subfamilies and the process of sequential changes in the respective source sequences were inferred. Despite the higher mutation rates of CG dinucleotides in individual dispersed members, no hypermutability of CG positions was observed in changes in the source sequences. This result suggests that sequences of SINEs located in a nonmethylated or hypomethylated genomic region could have been selected as source sequences for retroposition and/or that some CG sites are the parts of recognition sequences of retropositional machineries.
