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

The present report describes work examining the manner in which nonmalignant bone marrow stromal cells prevent acute lymphoblastic leukemia (ALL) cell death. The initial focus was on the role of stromal cell-derived C-X-C motif chemokine 12 (CXCL12). Interference with CXCL12 production by stroma or blockade of its interactions with ALL by plerixafor did increase ALL cell death and in sensitive ALLs there was synergistic effect with conventional chemotherapy drugs. However, in contrast to most reports, there was considerable heterogeneity regarding the effect between 7 unique primary ALLs, with several exhibiting no sensitivity to CXCL12 blockade. The diversity in effect was not explained by differences in the expression of ALL cell surface receptors for CXCL12. The modest and variable effects of interference with CXCL12 on ALL led to the assessment of gene expression profiles of stromal cells and ALL cells. Gene set enrichment analysis identified pathways associated with metabolism and redox reactions as potentially important in the stromal cell: leukemia cell interaction. Exploratory imaging studies demonstrated bidirectional transfer of intracellular calcien-labelled molecules and also bidirectional transfer of mitochondria between stromal cells and ALL cells, providing potential means of metabolic interdependence of stromal cells and ALL cells.
