Transient dsDNA breaks during pre-replication complex assembly.
Article in Nucleic acids research, 2009. 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
Initiation of DNA replication involves the ordered assembly of the multi-protein pre-replicative complex (pre-RC) during G(1) phase. Previously, DNA topoisomerase II (topo II) was shown to associate with the DNA replication origin located in the lamin B2 gene locus in a cell-cycle-modulated manner. Here we report that activation of both the early-firing lamin B2 and the late-firing hOrs8 human replication origins involves DNA topo II-dependent, transient, site-specific dsDNA-break formation. Topo IIbeta in complex with the DNA repair protein Ku associates in vivo and in vitro with the pre-RC region, introducing dsDNA breaks in a biphasic manner, during early and mid-G(1) phase. Inhibition of topo II activity interferes with the pre-RC assembly resulting in prolonged G(1) phase. The data mechanistically link DNA topo IIbeta-dependent dsDNA breaks and the components of the DNA repair machinery with the initiation of DNA replication and suggest an important role for DNA topology in origin activation.
