Murine spinal cord transcriptome analysis following reduction of prevalent myelin cDNA sequences.
Article in Cellular and molecular neurobiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
From 1,000 randomly selected colonies from cDNA libraries derived from murine spinal cord subtracted against white matter by means of suppression subtractive hybridization, 220 clones were identified as differentially expressed by dot blot analysis. Sequence analysis by the BLAST programming identified 140 unique genes. (1) The percentage of known sequences from myelin and other glial sources was reduced by approximately 75% over previous, similar subtractions employing visual cortex as the driver. (2) Differentially expressed genes tended to reflect existing expectations concerning structure and function of the spinal cord. (3) About 35% of all genes differentially expressed in the spinal cord in this study are also known to be differentially expressed for this structure as tabulated in the UniGene database. (4) About 33% of all genes differentially expressed in the present study are recorded as not present when measured in the spinal cord according to the UniGene database indicating that present techniques are not recording about a third of differentially expressed genes in this structure. (5) About 15% of all differentially expressed genes are for unknown, putative or hypothetical protein products. (6) About 4% of all differentially expressed genes are novel expressed sequence tags for the mouse. The current study demonstrates the importance of reducing the presence of glial associated sequences when comparing brain regions. It is concluded that the persistence of some myelin sequences in the spinal cord when white matter is used as the driver indicates that myelination is more active in this structure than for those areas represented by white matter and corpus callosum.
