Major chromosomal length polymorphisms are evident after meiosis in the phytopathogenic fungus Leptosphaeria maculans.
Article in Current genetics. 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
Chromosomal DNA of Australian field-isolates of the phytopathogenic ascomycete Leptosphaeria maculans was resolved by pulsed-field gel electrophoresis. All isolates examined had highly variable karyotypes. Ascospores (sexual spores) derived from single pseudothecia (sexual fruiting bodies) isolated from Brassica napus (oilseed rape) stubble were analyzed. In two tetrads four distinct karyotypes were observed, with only one chromosomal DNA band in common to all the members of each tetrad. Although isolates had highly variable karyotypes, two overall patterns were present. In one pattern there were at least 12 chromosomal DNA bands, the largest being greater than 2.2 Mb in size; in the other there were more than 15 chromosomal DNA bands, the largest being about 2.0 Mb. The chromosomal DNA preparations included mitochondrial DNA which migrated as a diffuse band between 0.10 and 0.15 Mb in size, and DNA molecules of 8 and 9 kb in size.
