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

objectiveThe purpose of this study was to evaluate the cytogenetic and fluorescent in situ hybridization (FISH) profile in children with acute lymphoblastic leukemia (ALL), referred to a university hospital in a 5-year 6-month period. SUBJECTS AND

methodsCytogenetic analysis of the bone marrow aspirate specimens of 91 patients was performed by standard Giemsa (G)-banding and interphase FISH (iFISH).

resultsThe frequency of chromosomal abnormalities detected by G-banding was 29.5%, and the frequency of nonrandom abnormalities with independent prognostic significance identified by iFISH was 46.4%. The abnormality with the highest frequency was gain of RUNX1 (n = 18, 21.4%), followed by ETV6/RUNX1 fusion (n = 7, 8.3%), and gain of KMT2A (n = 6, 7.1%). Additionally, rarely reported gains of ETV6, PBX1, and ABL1 were observed at a frequency of 6% (n = 5), and the deletion of ETV6 and TCF3 was seen at a frequency of 3.6% (n = 3) and 2.3% (n = 2), respectively. A 10-year old with intrachromosomal amplification of chromosome 21 was also observed.

conclusionsThis study strengthens and widens the current knowledge of the cytogenetic landscape of pediatric ALL.
