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
Recent molecular and morphological studies place Artiodactyla and Cetacea into the order Cetartiodactyla. Within the Cetartiodactyla such families as Bovidae, Cervidae, and Suidae are well studied by comparative chromosome painting, but many taxa that are crucial for understanding cetartiodactyl phylogeny remain poorly studied. Here we present the genome-wide comparative maps of five cetartiodactyl species obtained by chromosome painting with human and dromedary paint probes from four taxa: Cetacea, Hippopotamidae, Giraffidae, and Moschidae. This is the first molecular cytogenetic report on pilot whale, hippopotamus, okapi, and Siberian musk deer. Our results, when integrated with previously published comparative chromosome maps allow us to reconstruct the evolutionary pathway and rates of chromosomal rearrangements in Cetartiodactyla. We hypothesize that the putative cetartiodactyl ancestral karyotype (CAK) contained 25-26 pairs of autosomes, 2n = 52-54, and that the association of human chromosomes 8/9 could be a cytogenetic signature that unites non-camelid cetartiodactyls. There are no unambiguous cytogenetic landmarks that unite Hippopotamidae and Cetacea. If we superimpose chromosome rearrangements on the supertree generated by Price and colleagues, several homoplasy events are needed to explain cetartiodactyl karyotype evolution. Our results apparently favour a model of non-random breakpoints in chromosome evolution. Cetariodactyl karyotype evolution is characterized by alternating periods of low and fast rates in various lineages. The highest rates are found in Suina (Suidae+Tayasuidae) lineage (1.76 rearrangements per million years (R/My)) and the lowest in Cetaceans (0.07 R/My). Our study demonstrates that the combined use of human and camel paints is highly informative for revealing evolutionary karyotypic rearrangements among cetartiodactyl species.
