Interstitial telomeric sites and NORs in Hartmann's zebra (Equus zebra hartmannae) chromosomes.
Article in Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Interstitial telomeric sites (ITSs) are considered as signatures of chromosomal rearrangements that take place during karyotype evolution. Understanding that equids have undergone rapid karyotype evolution compared with the average in other mammals, a search of these signatures was carried out in the Hartmann's mountain zebra (Equus zebra hartmannae; EZH) chromosomes. Six consistent ITSs were identified on five of the zebra chromosomes (EZH1p, 1q, 2q, 5q, 6q and 11q). The location of these ITSs coincided with fusion points of some of the evolutionarily conserved human-Hartmann's zebra chromosomal segments suggesting that the sequences are remnants of fusion events between ancestral chromosomes. Incidentally, three of the ITSs also matched with the presence of constitutive heterochromatin. Further, ribosomal gene clusters were localized on five zebra chromosomes and the data were compared with those in other equid species. The findings offer preliminary evidence on the likely evolution of some of the Hartmann's zebra chromosomes and add to the current search for clues that lead to the ancestral chromosomal configuration in equids.
