Single molecule fluorescence analysis of branch migration of holliday junctions: effect of DNA sequence.
Article in Biophysical journal, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The Holliday junction is a central intermediate in various genetic processes including homologous, site-specific recombination and DNA replication. Recent single molecule FRET experiments led to the model for branch migration as a stepwise stochastic process in which the branch migration hop is terminated by the folding of the junction. In this article, we studied the effect of the sequence on Holliday junction dynamics and branch migration process. We show that a GC pair placed at the border of the homologous region almost prevents the migration into this position. At the same time, insertion of a GC pair into the middle of the AT tract does not show this effect, however when the junction folds at this position, it resides at this position much longer time in comparison to the folding at AT pairs. Two contiguous GC pairs do not block migration as well and generally manifest the same effect as one GC pair--the junction when it folds resides at these positions for a relatively long time. The same elevated residence time was obtained for the design with the homology region that consists of only GC pairs. These data suggest a model for branch migration in which the sequence modulates the overall stochastic process of the junction dynamics and branch migration by the variability of the time that the junction dwells before making a migration hop.
