High MN1 expression increases the in vitro clonogenic activity of primary mouse B-cells.

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
The MN1 (Meningioma 1) gene is overexpressed in certain subtypes of acute myeloid leukemia (AML) and high levels of MN1 expression in mouse bone marrow cells results in myeloid leukemia. We showed that compared with control bone marrow (BM) MN1 expression was increased (2-fold or more) in 29 out of 73 (40%) pediatric B-cell acute lymphoblastic leukemia (B-ALL) patient BM. Additional analysis of MN1 expression in sub-groups within our cohort carrying different chromosome translocations showed that carriers of the good prognostic marker t(12;21)(TEL-AML1) (n=27) expressed significantly more MN1 than both healthy controls (n=9) (P=0.02) and the group carrying the t(9;22)(BCR-ABL) (n=9) (P=0.001). In addition, AML1 expression was also upregulated in 31 out of 45 (68%) B-ALL patient BM compared with control and there was a significant correlation between MN1 and AML1 expression (r=0.3552, P=0.0167). Retroviral MN1 overexpression increased the colony forming activity of mouse Pro-B/Pre-B cells in vitro. Our results suggest that deregulated MN1 expression contributes to the pathogenesis of pediatric B-ALL. Further investigation into the clinical and biological significance of elevated MN1 expression in TEL-AML1(positive) leukemia might provide insight into additional molecular mechanisms contributing to B-ALL and may lead to improved treatment options for patients.
