Kin recognition in Aleochara bilineata could support the kinship theory of genomic imprinting.
Article in Genetics, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Genomic imprinting corresponds to the differential expression of a gene according to its paternal or maternal origin. The kinship theory of genomic imprinting proposes that maternally or paternally inherited genes may be in conflict over their effects on kin differently related along the paternal or maternal line. Most examples supporting the kinship theory of imprinting deal with competition between offspring for maternal resources. However, genomic imprinting may also explain differential behavioral expression toward kin whenever sibs are more related to each other via one parental sex than the other. Unfortunately, nothing is currently known about imprinting associated with a behavioral phenotype in insects. Here we report the first evidence of such a maternally imprinted behavior. We show that the solitary parasitoid larvae of Aleochara bilineata Gyll (Coleoptera; Staphylinidae), which avoid superparasitizing their full sibs, also avoid their cousins when they are related to them through their father, but not when they are related to them through their mother. A genetic kin recognition mechanism is proposed to explain this result and we conclude that genomic imprinting could control the avoidance of kin superparasitism in this species and have a profound influence on decision-making processes.
