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

Mixed phenotype acute leukaemia (MPAL) is a rare subtype of acute leukaemia possessing significant therapeutic challenges, as no standardized, evidence-based treatment regimen has been defined. In this nationwide study, we aimed to assess the effect of an acute lymphoid leukaemia (ALL)-like regimen; an acute myeloid leukaemia (AML)-like regimen; and a hybrid regimen on complete remission (CR), overall survival (OS) and event-free survival (EFS). Patients were identified through the Danish National Pathology Registry and validated according to the 2022 WHO classification. OS was estimated using the Kaplan-Meier estimator, and differences in OS were assessed with the log-rank test. Inverse probability weighting was used to balance compared groups with respect to age and calendar year. Among the 43 intensively treated WHO 2022 MPAL patients, 25 (58.1%) received ALL regimens, 10 (23.3%) received AML regimens and 8 (18.6%) received hybrid regimens. CR rates by treatment regimen were highest for hybrid regimen (87.5% (95% confidence interval (CI): 47.3%-99.7)), followed by ALL regimen (72% (95% CI: 50.6%-87.5%)) and AML regimen (40% (95% CI: 12.2%-73.8%)). Treatment with hybrid regimens consisting of a fludarabine-based approach (fludarabine, cytarabine, G-CSF and idarubicin [FLAG-IDA], fludarabine, cytarabine, G-CSF and mitoxantrone [Mito-FLAG] or fludarabine, etoposide, G-CSF, mitoxantrone and cytarabine [FLEGMA]) was associated with improved OS and EFS compared to a classic daunorubicin-cytarabine AML regimen (p = 0.02 and p = 0.002 respectively).
