Long-range organization and sequence-directed curvature of Xenopus laevis satellite 1 DNA.
Article in Nucleic acids research, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
We have investigated the long-range organization and the intrinsic curvature of satellite 1 DNA, an unusual tandemly-repeated DNA family of Xenopus laevis presenting sequence homologies to SINEs. PFGE was used in combination with frequent-cutter restriction enzymes not likely to cut within satellite 1 DNA and revealed that almost all the repeating units are tandemly organized to form large arrays (200 kb to 2 Mb) that are marked by restriction length polymorphism and contain intra-array domains of sequence variation. Besides that, we have analysed the secondary structure of satellite 1 DNA by computer modelling. Theoretical maps of curvature obtained from three independent models of DNA bending (the dinucleotide wedge model of Trifonov, the junction model of Crothers and the model of de Santis) showed that satellite 1 DNA is intrinsically curved and these results were confirmed experimentally by polyacrylamide gel electrophoresis. Moreover, we observed that this bending element is highly conserved among all the members of the satellite 1 DNA family that are accessible to analysis. A potential genetic role for satellite 1 DNA based on this unusual structural feature is discussed.
