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

Chronic lymphocytic leukemia (CLL) is a clinically and molecularly heterogeneous disease. PKMYT1, a G2/M cell cycle kinase, has been implicated in tumor progression in several cancers, but its role in CLL remains unclear. We evaluated PKMYT1 expression in primary CLL samples and analyzed associations with cytogenetic features and clinical parameters. PKMYT1 expression was heterogeneous and correlated with adverse features, including complex karyotype and elevated leukocyte counts. Comparative transcriptomic analyses between high- and low-expression groups revealed enrichment of pathways related to chromatin remodeling, DNA repair, and mitotic regulation. In MEC1 cells, pharmacological PKMYT1 inhibition significantly reduced cancer cell viability. PCR analysis showed upregulation of TP53, CASP3, BAK, GSDMD, BCL2, CASP1, IL1β, RIPK1, and RIPK3, indicating activation of apoptotic, inflammasome-associated, and necroptotic pathways. Collectively, these findings demonstrate that PKMYT1 is heterogeneously expressed in CLL, associated with adverse cytogenetic and clinical features, and critical for cell survival, highlighting its potential as a therapeutic target.
