Purification of leukemic blast cells from blood smears using laser microdissection.
Article in International journal of hematology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
In treatment of acute myeloid leukemia (AML), prognostic factors, including gene mutation and abnormal gene expression, enable risk stratification of patients. However, in the case of a small proportion of leukemic blast cells, such as AML associated with Down syndrome (AML-DS), it is not possible to examine prognostic factors precisely due to the large proportion of normal cells. Here, we present a novel method for examining prognostic factors by making a smear on a membrane slide glass from a small amount of diagnostic specimen and collecting highly pure leukemic blast cells by laser microdissection (LMD). We verified the effectiveness of this method using 10% KPAM1 cell line suspension and peripheral blood containing 20% blast cells obtained from a patient with transient abnormal myelopoiesis (TAM). After making blood smears, approximately 100 cells were collected and analyzed by direct sequencing. Frameshift mutations (2 bp deletion and 17 bp duplication, respectively) in GATA-1 were detected in each sample, suggesting KPAM1 and TAM blast cells were accurately purified. This novel method enables us to precisely examine prognostic factors in many cases, even in cases with a small proportion of leukemic blast cells or small specimens to preserve.
