Functional features of a single chromosome arm in wheat (1AL) determined from its structure.
Article in Functional & integrative genomics, 2012. 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
Bread wheat (Triticum aestivum L.) is one of the most important crops globally and a high priority for genetic improvement, but its large and complex genome has been seen as intractable to whole genome sequencing. Isolation of individual wheat chromosome arms has facilitated large-scale sequence analyses. However, so far there is no such survey of sequences from the A genome of wheat. Greater understanding of an A chromosome could facilitate wheat improvement and future sequencing of the entire genome. We have constructed BAC library from the long arm of T. aestivum chromosome 1A (1AL) and obtained BAC end sequences from 7,470 clones encompassing the arm. We obtained 13,445 (89.99%) useful sequences with a cumulative length of 7.57 Mb, representing 1.43% of 1AL and about 0.14% of the entire A genome. The GC content of the sequences was 44.7%, and 90% of the chromosome was estimated to comprise repeat sequences, while just over 1% encoded expressed genes. From the sequence data, we identified a large number of sites suitable for development of molecular markers (362 SSR and 6,948 ISBP) which will have utility for mapping this chromosome and for marker assisted breeding. From 44 putative ISBP markers tested 23 (52.3%) were found to be useful. The BAC end sequence data also enabled the identification of genes and syntenic blocks specific to chromosome 1AL, suggesting regions of particular functional interest and targets for future research.
