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

Chromosomal scaffold-associated DNA has been isolated from pea leaf nuclei treated with lithium diiodosalicylate to remove histones and then digested with restriction enzymes to remove the DNA in chromosomal loops. A scaffold-associated region (SAR) of DNA has been identified 8 to 9 kb downstream of the single-copy pea plastocyanin gene in proximity to a repetitive sequence present in 300 copies in the pea haploid genome. Isolated restriction fragments from within the SAR can bind to scaffold preparations in a binding assay in vitro. The nucleotide sequence of the SAR indicates a 540-bp 77% A+T-rich region containing many sequence elements in common with SARs from other organisms. Sequences with homology to topoisomerase II binding sites, A-box and T-box sequences, and replication origins are present within this AT-rich region.
