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 myelin sheath in the vertebrate CNS is formed by oligodendrocytes. The number of oligodendrocytes in a mature axon tract must be sufficient to myelinate all appropriate axons. How the number of oligodendrocytes is matched to axonal requirements and whether such matching involves axon-oligodendrocyte signaling or intrinsic oligodendrocyte self-regulation are not clear. Using a combination of in vitro analyses, we demonstrate that oligodendrocyte precursors closely regulate their numbers through interactions between adjacent precursors. In low-density rat spinal cord cultures, the number of oligodendrocyte lineage cells increases rapidly. The addition of large numbers of oligodendrocyte precursors substantially reduces precursor expansion and results in a normalization of oligodendrocyte lineage cell numbers in the cultures over time. Thus, the number of oligodendrocyte lineage cells that develop appears dependent on the density of oligodendrocyte lineage cells. This normalization of cell number is reflected in assays of clonal potential and proliferation. For example, precursors gave rise to fewer progeny and proliferated less at high density. Reduced precursor expansion at high density was not attributable to the depletion of growth factors. Cocultures of high and low densities did not inhibit precursor expansion in low-density cultures, suggesting the requirement for local cell-cell interactions. The inhibition of precursor expansion was cell-type-specific and dependent on the presence of oligodendrocyte lineage cells. We propose that this density-dependent feedback inhibition of oligodendrocyte precursor expansion may play a primary role in regulating the number of oligodendrocytes in the developing spinal cord.
