Binding of sequences from the 5'- and 3'-nontranscribed spacers of the rat rDNA locus to the nucleolar matrix.
Article in Chromosoma, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
Nucleolar matrix structures were obtained under different extraction conditions from highly purified isolated nucleoli. Their ultrastructural appearance, protein composition and capacity to bind rDNA preferentially were studied in a model binding system. A region spanning approximately 25 kb in the rat ribosomal gene locus was screened for DNA sites capable of specifically interacting with the proteins of the nucleolar matrix (MARs). Two such sites were identified: one is located on an EcoRV-KpnI fragment in the 5'-nontranscribed spacer region, between two repetitive elements and close to the transcription initiation site; the other MAR is on a PvuII-BamHI fragment located in the 3'-nontranscribed region, encompassing an element 85% homologous to a B2-sequence. The two MARs are located in regions rich in polypyrimidine/polypurine tracks and contain a few elements homologous to the consensus sequence for topoisomerase II. This indicates that the "attachment sites" for the ribosomal genes belong to the same class of sequences as the MARs attaching the chromosomal DNA to the nuclear matrix.
