Two different and functional nuclear rDNA genes in the abalone Haliotis tuberculata: tissue differential expression.
Article in Genetica, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Analysis of the 18S rDNA sequences of Haliotis tuberculata tuberculata and H. t. coccinea subtaxa identified two different types of 18S rDNA genes and ITS1 regions. These two different genes were also detected in H. marmorata, H. rugosa and H. diversicolor that are separated from H. tuberculata by 5-65 mya. The mean divergence value between type I and type II sequences ranged from 7.25% for 18S to 80% for ITS1. ITS1 type II is homologous with the ITS1 consensus sequences published for many abalone species, whereas ITS1 type I presented only minor homology with a unique database entry for H. iris ITS1. A phylogenetic analysis makes a clear separation between type I and type II ITS1 sequences and supports grouping H. t. tuberculata, H. t. coccinea and H. marmorata together. The two subtaxa do not show any significant differences between the homologous 18S rDNA sequences. A general structure of the ITS1 transcript was proposed, with four major helices for the two types. The two genes were expressed and, for the first time, a putative differential expression of ITS1 type I was detected in the gills, digestive gland and gonads whereas ITS1 type II was expressed in all tissues.
