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
Homoeologous metaphase I (MI) pairing of Triticum aestivum x Aegilops geniculata hybrids (2n = 5x = 35, ABDU(g)M(g)) has been examined by an in situ hybridization procedure permitting simultaneous discrimination of A, B, D and wild genomes. The seven D genome chromosomes (and their arms, except for 6D and 7D) plus some additional wheat chromosomes were also identified. Wheat-wild MI associations represented more than 60% of total, with an average ratio of 5:1:12 for those involving the A, B and D genomes, respectively. A remarkable between-chromosome variation for the level of wheat-wild genetic exchange is expected within each wheat genome. However, it can be concluded that 3DL and 5DL are the crop genome locations with the highest probability of being transferred to Ae. geniculata. Hybrids derived from the ph2b wheat mutant line showed increased MI pairing but identical pattern of homoeologous associations than those with active Ph2.
