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
Chicken (Gallus gallus domesticus, GGA) and Japanese quail (Coturnix coturnix japonica, CCO) karyotypes are very similar. They have identical chromosome number (2n = 78) and show a high degree of synteny. Centromere positions on the majority of orthologous chromosomes are different in these two species. To explore the nature of this divergence, we used high-resolution comparative fluorescent in situ hybridization mapping on giant lampbrush chromosomes (LBCs) from growing oocytes. We applied 41 BAC clones specific for GGA1, 2, 3, 11, 12, 13, 14, and 15 to chicken and quail LBCs. This approach allowed us to rule out a pericentric inversion earlier proposed to explain the difference between GGA1 and CCO1. In addition to a well-established large-scale pericentric inversion that discriminates GGA2 and CCO2, we identified another, smaller one in the large inverted region. For the first time, we described in detail inversions that distinguish GGA3 from CCO3 and GGA11 from CCO11. Despite the newly identified and confirmed inversions, our data suggest that, in chicken and Japanese quail, the difference in centromere positions is not mainly caused by pericentric inversions but is instead due to centromere repositioning events and the formation of new centromeres. We also consider the formation of short arms of quail microchromosomes by heterochromatin accumulation as a third scenario that could explain the discrepancy in centromeric indexes.
