Chromosome evolution in bears: reconstructing phylogenetic relationships by cross-species chromosome painting.
Article in Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Genome-wide homology maps among dog (Canis familiaris, CFA, 2n = 78), African lion (Panthera leo, PLE, 2n = 38), clouded leopard (Neofelis nebulosa, NNE, 2n = 38) and Malayan sun bear (Helartos malayanus, HMA, 2n = 74) have been established by chromosome painting using a complete set of dog probes. In total, chromosome-specific painting probes from the 38 dog autosomes reveal 69, 69 and 73 conserved segments in African lion, clouded leopard and Malayan sun bear, respectively. The chromosomal painting results show that the African lion and clouded leopard have an identical karyotype which, in turn, is similar to that previously published for the cat (Felis catus, FCA 2n = 38). The findings confirm and extend other studies that show felids to be karyotypically conserved. In contrast, ursids, including the Malayan sun bear, have a relatively highly rearranged karyotype in comparison with other carnivores. The 2n = 74 karyotype of the Malayan sun bear, which is believed to closely resemble the ancestral karyotype of the Ursidae, could have evolved from the 2n = 42 putative ancestral carnivore karyotype by an inversion and 16 centric fissions. Independent fusions of the acrocentric ancestral chromosomes have generated the unique karyotypes of the giant panda and the spectacled bear.
