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
key messageA chromosomal inversion associated with the tomato Ty - 2 gene for TYLCV resistance is the cause of severe suppression of recombination in a tomato Ty - 2 introgression line. Among tomato and its wild relatives inversions are often observed, which result in suppression of recombination. Such inversions hamper the transfer of important traits from a related species to the crop by introgression breeding. Suppression of recombination was reported for the TYLCV resistance gene, Ty-2, which has been introgressed in cultivated tomato (Solanum lycopersicum) from the wild relative S. habrochaites accession B6013. Ty-2 was mapped to a 300-kb region on the long arm of chromosome 11. The suppression of recombination in the Ty-2 region could be caused by chromosomal rearrangements in S. habrochaites compared with S. lycopersicum. With the aim of visualizing the genome structure of the Ty-2 region, we compared the draft de novo assembly of S. habrochaites accession LYC4 with the sequence of cultivated tomato ('Heinz'). Furthermore, using populations derived from intraspecific crosses of S. habrochaites accessions, the order of markers in the Ty-2 region was studied. Results showed the presence of an inversion of approximately 200 kb in the Ty-2 region when comparing S. lycopersicum and S. habrochaites. By sequencing a BAC clone from the Ty-2 introgression line, one inversion breakpoint was identified. Finally, the obtained results are discussed with respect to introgression breeding and the importance of a priori de novo sequencing of the species involved.
