One-way PCR-based mapping of a replication initiation point (RIP).
Article in Nature protocols, 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 lamin B2 locus is the only mammalian origin whose replication initiation points (RIPs) have been mapped. Although this paper was published 8 years ago, no further mammalian RIP-mapping studies have been reported, largely due to technical difficulties of ligation-mediated (LM)-PCR used by the authors. Here, we report the development of a simple, one-way PCR-based protocol that allows one to accurately determine RIPs at mammalian origins. The procedure can be completed within 48 h from the time of cell lysis in the agarose gel. Nascent DNA is then isolated from the same gel after DNA is separated by alkaline gel electrophoresis. Subsequently, RIPs are determined by one-way PCR-based primer extension using labeled primers. Using this protocol, we have successfully mapped RIPs in the human DBF4 locus. As one-way PCR is routinely used by many scientists, this protocol will provide a powerful new tool for studying DNA replication in many organisms including mammalian cells.
