The association between financial toxicity and mortality in hematologic malignancies: a systematic review and meta-analysis.
Synthesis in The oncologist, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHematologic malignancies impose substantial economic burdens, but the quantitative association between financial toxicity and overall survival remains poorly defined across diverse clinical settings and disease lineages.
methodsAdhering to PRISMA and MOOSE guidelines, we searched electronic databases through January 2026 for studies reporting multivariable-adjusted hazard ratios (aHRs) for the association between financial toxicity and mortality in adults diagnosed with hematologic malignancies. A random-effects model with Hartung-Knapp adjustment was used for data synthesis. Small-study effects were addressed via the Duval and Tweedie trim-and-fill method.
resultsEleven cohorts involving 280 826 individuals were included. Meta-analysis identified a significant association between financial toxicity and inferior survival (pooled aHR: 1.57; 95% CI, 1.29-1.91; P < .001). High heterogeneity (I2 = 85.1%) and a wide 95% prediction interval (0.89-2.77) indicated substantial variability across settings. Subgroup analysis revealed that mortality risk was primarily linked to structural barriers, specifically lack of insurance (aHR: 1.66; 95% CI, 1.39-1.99), whereas this association was weaker in specialized transplant settings with integrated psychosocial support. Findings remained statistically significant after trim-and-fill adjustment for potential publication bias (adjusted aHR: 1.33; 95% CI, 1.05-1.69; P = .023).
conclusionsFinancial toxicity is a significant factor independently associated with mortality in hematologic malignancies. The strength of this association varies depending upon the care environment, with structural access barriers representing the highest risk. Integrating proactive financial navigation into standard clinical pathways is essential to alleviate socioeconomic disparities and may help improve survival outcomes.
