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
Systematic investigations on the occurrence of differential DNA replication in carrot cultures, expressed at the total genome level, were performed. The genome of Daucus carota L. could be characterized by a pattern of repetitive BstNI fragments that was independent of tissue specificity or cultivar differences. Characterization of the genomic DNA of the secondary phloem of carrot roots, in comparison to the DNA of the induced primary cultures at different growth phases, revealed dramatic differences in the copy number of the repetitive fragments. Highly proliferative tissue showed extensive reduction in the proportion of repetitive sequences in the genome in all of the 37 investigated variants. In contrast, during subsequent transition to stationary growth the repetitive fragments re-amplified. The results suggest that the quantitative genome organisation was involved in the regulation of the growth potential of cells. A hypothesis is discussed suggesting a determining influence of the observed differential DNA replication on cell-cycle rates and the cell program of proliferative tissue by structural and positioning effects on DNA loops. To study the causality of somaclonal variation, research on the relationship between physiological genome variability and the induction of heritable changes is recommended.
