Cell confinement initiates a delayed but heritable loss of chromosomes.
Article in Cell reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Heritable genetic changes continually arise in cancer, especially in solid tumors where cells are sometimes compressed. Rare heritable losses of chromosomes in live cells are quantified here with chromosome reporters (ChReporters), which reveal losses only after imposing a threshold level of confinement. Compression to ∼60% of interphase height ruptures few nuclei compared to deeper compression but perturbs mitotic spindles and prolongs pro/metaphase. Chromosome mis-segregation into micronuclei is discovered only after release from modest confinement, but arrest and death predominate. All such effects are phenocopied by nocodazole washout, which generates a "memory" of prolonged mitosis. The effects also differ from the rapid induction of micronuclei by a spindle-assembly checkpoint inhibitor and by a clinical CDK4/6 inhibitor of cell-cycle entry. Single-cell RNA sequencing confirms chromosome loss days after confinement and reveals dysregulation of chromosome-segregation pathways. Chromosome losses as mitotic memories of confinement ultimately address knowledge gaps in mechanobiology and cancer evolution.
