Characteristics of the tomato nuclear genome as determined by sequencing undermethylated EcoRI digested fragments.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
A collection of 9,990 single-pass nuclear genomic sequences, corresponding to 5 Mb of tomato DNA, were obtained using methylation filtration (MF) strategy and reduced to 7,053 unique undermethylated genomic islands (UGIs) distributed as follows: (1) 59% non-coding sequences, (2) 28% coding sequences, (3) 12% transposons-96% of which are class I retroelements, and (4) 1% organellar sequences integrated into the nuclear genome over the past approximately 100 million years. A more detailed analysis of coding UGIs indicates that the unmethylated portion of tomato genes extends as far as 676 bp upstream and 766 bp downstream of coding regions with an average of 174 and 171 bp, respectively. Based on the analysis of the UGI copy distribution, the undermethylated portion of the tomato genome is determined to account for the majority of the unmethylated genes in the genome and is estimated to constitute 61+/-15 Mb of DNA (approximately 5% of the entire genome)--which is significantly less than the 220 Mb estimated for gene-rich euchromatic arms of the tomato genome. This result indicates that, while most genes reside in the euchromatin, a significant portion of euchromatin is methylated in the intergenic spacer regions. Implications of the results for sequencing the genome of tomato and other solanaceous species are discussed.
