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
In eukaryotes, the origin recognition complex (ORC) promotes the assembly of minichromosome maintenance 2 to 7 complexes into a head-to-head double hexamer at origin DNA in a process known as replication licensing. In this study, we present a series of cryoelectron microscopy structures of yeast ORC mutants in complex with origin DNA. We show that Orc6, the smallest subunit of ORC, utilizes its transcription factor II B-B domain to orchestrate the sequential binding of ORC to origin DNA. In addition, Orc6 plays the role of a scaffold by stabilizing the basic patch (BP) of Orc5 for ORC to capture and bend origin DNA. Importantly, disrupting DNA bending through mutating three key residues in Orc5-BP impairs ORC's ability to promote replication initiation at two points during the pre-RC assembly process. This study dissects the multifaceted role of Orc6 in orchestrating ORC's activities on DNA and underscores the vital role of DNA bending by ORC in replication licensing.
