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
Modern sugarcane cultivars are derived from the hybridization of Saccharum officinarum (2n = 80) and S. spontaneum (2n = 40-128), leading to a variety of complex genomes with highly polyploid and varied chromosome structures. These complex genomes have hindered deciphering the genome structure and marker-assisted selection in sugarcane breeding. Ten cultivars were analyzed by fluorescence in situ hybridization adopting chromosome painting and S. spontaneum-specific probes. The results showed six types of chromosomes in the studied cultivars, including S. spontaneum or S. officinarum chromosomes, interspecific recombinations from homoeologous or nonhomoeologous chromosomes, and translocations of S. spontaneum or S. officinarum chromosomes. The results showed unexpectedly high proportions of interspecific recombinations in these cultivars (11.9-40.9%), which renew our knowledge that less than 13% of chromosomes result from interspecific exchanges. Also, the results showed a high frequency of translocations (an average of 2.15 translocations per chromosome) between S. officinarum chromosomes. The diverse types of chromosomes in cultivars imply that hybrid gametes of S. spontaneum and S. officinarum may form unusual chromosome pairs, including homoeologous or nonhomoeologous chromosomes either between or within S. spontaneum and S. officinarum. Moreover, we consistently observed 11 or 12 copies for the four studied chromosomes, i.e., chromosomes 1, 2, 7, and 8, suggesting steady transmission during the breeding program. By comparison, we found a relatively fewer copies of S. spontaneum chromosome 1 than those of S. spontaneum chromosomes 2, 7, and 8. These results provide deep insights into the structure of cultivars and may facilitate chromosome-assisted selection in sugarcane breeding.
