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 by fluorescence in situ hybridization (FISH) the synteny between Brachypodium distachyon with a small genome (1C = 320 Mb) and barley with a large genome (1C = 5,100 Mb) at the chromosome level. Reciprocal genomic in situ hybridization (GISH) between B. distachyon and barley labeled mainly 45S ribosomal DNA loci, indicating that most high copy DNA is weakly conserved between both grasses. Of 13 BAC clones with inserts from different B. distachyon chromosomes, only two belonging to chromosome 1 yielded hybridization signals on a barley metaphase chromosome (on 7HS and 7HL, respectively), confirming synteny between both chromosomes. FISH experiments to characterize the synteny of single-copy loci were performed. Two of four Brachypodium sylvaticum BACs spanning a 223-kb interval homologous to the region of barley that harbors a gibberellic-acid-insensitive semi-dwarfing gene, sdw3, hybridized specifically to a central position of B. distachyon chromosome 1 short arm but not to the homologous region of the barley genome. Repeat-free sequences PCR amplified from four non-overlapping barley BACs linked to the core of Sdw3 region yielded signals at distinct positions in the middle of barley chromosome arm 2HS. Together, these results (1) confirmed the synteny between B. distachyon chromosome 1 and barley chromosomes 2H and 7H at the cytological level, (2) indicated mid-arm position for the Sdw3 locus genetically mapped at the centromere of barley chromosome 2H, and (3) proved that the sdw3 core interval of < 100 kb in B. distachyon corresponds to a megabase-sized syntenic region in barley.
