Characterization and prediction of prolonged severe neutropenia in pediatric patients receiving tisagenlecleucel.
Article in Blood advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
abstractHematotoxicity is the most frequent severe toxicity after chimeric antigen receptor T-cell (CAR-T) therapy. However, limited data exist on risk factors and outcomes for hematotoxicity for children and young adults (CAYAs) with B-acute lymphoblastic leukemia treated with tisagenlecleucel. We conducted a multi-institutional study involving 326 CAYAs, with 144 evaluable in an initial training cohort and 141 evaluable in a validation cohort, through the Pediatric Real-World CAR Consortium to characterize the incidence and outcomes of prolonged severe neutropenia (PSN) and to develop a predictive risk score for PSN, tailored for use in this population. The incidence of PSN, defined as an absolute neutrophil count of <0.5 x 103 cells per μL for ≥30 days, was 15.3% in the initial training cohort and 21% in the validation cohort. Development of PSN was associated with inferior overall survival (P < .001), relapse-free survival (P = .01), higher nonrelapse mortality (P = .003), and a greater risk of infections within 30 days (P = .03). Multivariable penalized regression analysis identified key risk factors for PSN, which included preinfusion C-reactive protein and bone marrow disease burden, and postinfusion peak ferritin and occurrence of severe cytokine release syndrome, which were used to create the CytoRisk score. In the validation cohort, the CytoRisk score discriminated between patients with and without PSN (area under the curve, 0.90; specificity, 93%; sensitivity, 71%; positive predictive value, 74%; and negative predictive value, 92%). The CytoRisk score may be used to a priori identify patients at highest risk of PSN and overall worse outcomes.
