Centromere retention and loss during the descent of maize from a tetraploid ancestor.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 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
Although centromere function is highly conserved in eukaryotes, centromere sequences are highly variable. Only a few centromeres have been sequenced in higher eukaryotes because of their repetitive nature, thus hindering study of their structure and evolution. Conserved single-copy sequences in pericentromeres (CSCPs) of sorghum and maize were found to be diagnostic characteristics of adjacent centromeres. By analyzing comparative map data and CSCP sequences of sorghum, maize, and rice, the major evolutionary events related to centromere dynamics were discovered for the maize lineage after its divergence from a common ancestor with sorghum. (i) Remnants of ancient CSCP regions were found for the 10 lost ancestral centromeres, indicating that two ancient homeologous chromosome pairs did not contribute any centromeres to the current maize genome, whereas two other pairs contributed both of their centromeres. (ii) Five cases of long-distance, intrachromosome movement of CSCPs were detected in the retained centromeres, with inversion the major process involved. (iii) The 12 major chromosomal rearrangements that led to maize chromosome number reduction from 20 to 10 were uncovered. (iv) In addition to whole chromosome insertion near (but not always into) other centromeres, translocation and fusion were found to be important mechanisms underlying grass chromosome number reduction. (v) Comparison of chromosome structures confirms the polyploid event that led to the tetraploid ancestor of modern maize.
