del(8p) and TNFRSF10B loss are associated with a poor prognosis and resistance to fludarabine in chronic lymphocytic leukemia.

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
Chronic lymphocytic leukemia (CLL) is a heterogeneous disease, the prognosis of which varies according to the cytogenetic group. We characterized a rare chromosomal abnormality (del(8p), deletion of the short arm of chromosome 8) in the context of CLL. By comparing the largest cohort of del(8p) CLL to date (n = 57) with a non-del(8p) cohort (n = 155), del(8p) was significantly associated with a poor prognosis, a shorter time to first treatment, worse overall survival (OS), and a higher risk of Richter transformation. For patients treated with fludarabine-based regimens, the next-treatment-free survival and the OS were shorter in del(8p) cases (including those with mutated IGHV). One copy of the TNFRSF10B gene (coding a pro-apoptotic receptor activated by TRAIL) was lost in 91% of del(8p) CLL. TNFRSF10B was haploinsufficient in del(8p) CLL, and was involved in the modulation of fludarabine-induced cell death - as confirmed by our experiments in primary cells and in CRISPR-edited TNFRSF10B knock-out CLL cell lines. Lastly, del(8p) abrogated the synergy between fludarabine and TRAIL-induced apoptosis. Our results highlight del(8p)'s value as a prognostic marker and suggest that fit CLL patients (i.e. with mutated IGHV and no TP53 disruption) should be screened for del(8p) before the initiation of fludarabine-based treatment.
