The possible evolutionary significance of repeat elements near and within an early chorion gene in the late chorion locus of Bombyx mori.
Article in Journal of molecular evolution, 1992. 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
Three beta-type early chorion gene copies (6F6.1, 6F6.2, and 6F6.3) are dispersed in the late region of chorion locus Ch1-2. Detailed analysis of the 5'-flanking region and the intron of 6F6.1 shows that they contain sequences that are homologous to Bombyx mori Bm1 repeat elements. Interestingly, the Bm1-type segment of the intron is interrupted by the insertion of a sequence that shows significant similarities with part of an intron of B. mori and Bombyx mandarina fibroin genes, and with part of the 3'-flanking region of B. mori prothoracicotropic hormone and tRNA-Glu genes; this sequence may represent a new repetitive, possibly transposable, element of B. mori. Following the Bm1-homologous sequence of the 6F6.1 5'-flanking region and preceding the gene promoter region, a short DNA segment shows sequence motifs that are also present in the ErA.1 promoter region. The occurrence of these sequences near one end or within the Bm1 repeat element is suggestive of complex sequence transfer events. Comparative analysis of known B. mori chorion alpha-gene promoters and of Bm1 repeat elements suggests, with marginal statistical significance, that these two sets of sequences contain common elements.
