Evolution of Tribolium madens (Insecta, Coleoptera) satellite DNA through DNA inversion and insertion.
Article in Journal of molecular evolution, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Two different satellite DNAs from tenebrionid species Tribolium madens (Insecta, Coleoptera) have been detected, cloned, and sequenced. Satellite I comprises 30% of the genome; it has a monomer size of 225 bp and a high A + T content of 74%. Satellite II, with a monomer size of 711 bp and A + T content of 70%, is less abundant, making 4% of the total DNA. Sequence variability of the monomers relative to consensus sequence is 4.1% and 1.2% for satellite I and II, respectively. Both satellites are localized in the heterochromatic regions of all chromosomes. A search for internal motifs showed that both satellites contain a related subsequences, about 100 bp long. The creation of satellite I monomer is explained by duplication of the basic subunit, followed by subsequent divergence by single point mutations, deletions, and gene conversion. Inversion of the subsequence in addition to its duplication has occurred in satellite II. The result of this inversion is possible formation of a long, stable dyad structure. The 408-bp sequence, inserted within satellite II monomer, shares no similarity with a basic subunit. Frequent direct repeats found within the inserted sequence point to its evolution by duplication of shorter motifs. It is proposed that both satellites have been derived from a common ancestral sequence whose duplication played a major role in the formation of satellite I monomer, while insertion of a new sequence together with inversion of an ancestral one induced the occurrence of satellite II.
