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

backgroundBrain-derived neurotrophic factor (BDNF) and its receptor, tropomyosin-related receptor kinase B (TrkB) are involved in the maturation of B lymphocytes in the bone marrow (BM), promote cell differentiation in B-cell malignancies, and are associated with poor prognosis in adults with acute leukemia (AL). However, the role of BDNF in pediatric AL remains poorly understood.

objectiveWe carried out a cohort observational study to evaluate BDNF levels in BM or peripheral blood (PB) samples from children with AL.

methodsBM or PB samples were collected from 57 children and adolescents with acute lymphoid leukemia (ALL), 14 children and adolescents with acute myeloid leukemia (AML), and 44 healthy individuals (HI) of the same age range.

resultsBDNF levels at diagnosis in AL patients were significantly lower when compared to HI. Samples from patients in complete remission from disease had higher levels of BDNF compared to those obtained from patients with malignant cells. Moreover, BDNF levels at diagnosis in patients who died were significantly lower compared to those found in survivors.

conclusionsThese findings provide the first evidence for a possible role of BDNF as a marker of active disease and poor prognosis in pediatric AL.
