1 · What the graph read from it

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.

2 · The registry

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 animal somatic cells, bipolar spindle formation requires separation of the centrosome-based spindle poles. Centrosome separation relies on multiple pathways, including cortical forces and antiparallel microtubule (MT) sliding, which are two activities controlled by the protein kinase aurora A. We previously found that depletion of the human kinetochore protein Mcm21R(CENP-O) results in monopolar spindles, raising the question as to whether kinetochores contribute to centrosome separation. In this study, we demonstrate that kinetochores promote centrosome separation after nuclear envelope breakdown by exerting a pushing force on the kinetochore fibers (k-fibers), which are bundles of MTs that connect kinetochores to centrosomes. This force is based on poleward MT flux, which incorporates new tubulin subunits at the plus ends of k-fibers and requires stable k-fibers to drive centrosomes apart. This kinetochore-dependent force becomes essential for centrosome separation if aurora A is inhibited. We conclude that two mechanisms control centrosome separation during prometaphase: an aurora A-dependent pathway and a kinetochore-dependent pathway that relies on k-fiber-generated pushing forces.
