Silk moth chorion pseudogenes: hallmarks of genomic evolution by sequence duplication and gene conversion.

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
The part of the genetic locus of the domesticated silk moth, Bombyx mori, in which high cysteine (Hc) chorion genes of late developmental specificity reside contains regions encompassing gene-like sequences which exhibit properties distinct from those of functional Hc genes. One of these regions has been characterized and shown to contain a chorion pseudogene, psi HcB.15, which shares pronounced similarities with a transcribed chorion pseudogene, psi HcB.12/13, which was characterized previously. Both pseudogenes are homologous to HcB chorion genes but bear multiple single nucleotide substitutions and short segmental mutations (insertions and deletions) which introduce translational frame shifts and termination codons in the coding regions. Structural characteristics unique to the two pseudogenes suggest that psi HcB.15 was generated first from a functional HcB gene and gave rise subsequently to psi HcB 12/13 as a result of a sequence duplication event. The two pseudogenes can be distinguished from each other by the presence of distinct regions of similarity to the consensus sequence of functional HcB genes which appear to have arisen from gene-conversion-mediated correctional events. These findings lend support to the hypothesis that chorion pseudogene sequences represent reservoirs of genetic information that participates in the evolution of the chorion locus rather than relics of inactivated genes passively awaiting extinction.
