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
Interstitial telomeric repeats (ITRs) were reported in a number of animal and plant species. Most ITRs are organized as short tandem arrays and are likely evolutionary relics derived from chromosomal rearrangements and DNA repairs. However, megabase-sized ITR arrays were reported in Solanum species. Here, we report a fluorescence in situ hybridization (FISH) survey of ITRs in all representative diploid Solanum species, including potato, tomato, and eggplant. FISH revealed massive amplification of ITRs in the centromeric regions of chromosomes from the Solanum species containing the B and P genomes. A significant proportion of the ITR FISH signals was mapped within the primary constrictions of the pachytene chromosomes of Solanum pinnatisectum (B genome). In addition, some ITR sites overlapped with St49, a satellite repeat enriched in centromeric DNA sequences associated with CENH3 nucleosomes, in both A and B genome Solanum species. These results show that some ITR subfamilies have been amplified and invaded in the functional centromeres of chromosomes in Solanum species.
