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
Insectivore-like animals are traditionally believed among the first eutherian mammals that have appeared on the earth. The modern insectivores are thus crucial for understanding the systematics and phylogeny of eutherian mammals as a whole. Here cross-species chromosome painting, with probes derived from flow-sorted chromosomes of human, was used to delimit the homologous chromosomal segments in two Soricidae species, the common shrew (Sorex araneus, 2n = 20/21), and Asiatic short-tailed shrew (Blarinella griselda, 2n = 44), and one Erinaceidae species, the shrew-hedgehog (Neotetracus sinensis, 2n = 32), and human. We report herewith the first comparative maps for the Asiatic short-tailed shrew and the shrew-hedgehog, in addition to a refined comparative map for the common shrew. In total, the 22 human autosomal paints detected 40, 51 and 58 evolutionarily conserved segments in the genomes of common shrew, Asiatic short-tailed shrew, and shrew-hedgehog, respectively, demonstrating that the common shrew has retained a conserved genome organization while the Asiatic short-tailed shrew and shrew-hedgehog have relatively rearranged genomes. In addition to confirming the existence of such ancestral human segmental combinations as HSA 3/21, 12/22, 14/15 and 7/16 that are shared by most eutherian mammals, our study reveals a shared human segmental combination, HSA 4/20, that could phylogenetically unite the Eulipotyphlan (i.e., the core insectivores) species. Our results provide cytogenetic evidence for the polyphyly of the order Insectivora and additional data for the eventual reconstruction of the ancestral eutherian karyotype.
