Occan, a novel transposon in the Fot1 family, is ubiquitously found in several Magnaporthe grisea isolates.
Article in Current genetics, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
We investigated a DNA fragment and its flanking region deleted in the spontaneous Pi-a virulent mutant of Magnaporthe grisea Ina168. A new transposon-like sequence was identified from a region adjacent to the deleted fragment and was named Occan. Occan contained a 2,259-bp ORF interrupted by one 63-bp intron and had both a TA dinucleotide and 77 bp of perfect inverted repeats at both termini, without direct repeats. These features indicated that Occan is a member of the Fot1 family. RT-PCR analysis confirmed the expression of the putative transposase and the presence of an intron. Southern analysis of pulse-field gel electrophoresis-separated chromosomes indicated that Occan was dispersed in all chromosomes of the rice pathogen, Ina168. Copy numbers of Occan were also preserved in a host-specific manner amongst M. grisea isolates. In particular, rice pathogens contained a large number of the element inserted into their genome. Phylogenetic analysis with other known members of the Fot1 family revealed that Occan was dissimilar to any other known elements and it is thus proposed that Occan be separated to a new subfamily.
