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

backgroundDuring cerebral cortex development, multipotent neural progenitor cells generate a variety of neuronal subtypes in a fixed temporal order. How a single neural progenitor cell generates the diversity of cortical projection neurons in a temporal sequence is not well understood. Based on their function in developmental timing in other systems, Dicer and microRNAs are potential candidate regulators of cellular pathways that control lineage progression in neural systems.

resultsCortex-specific deletion of Dicer results in a marked reduction in the cellular complexity of the cortex, due to a pronounced narrowing in the range of neuronal types generated by Dicer-null cortical stem and progenitor cells. Instead of generating different classes of lamina-specific neurons in order over the 6-day period of neurogenesis, Dicer null cortical stem and progenitor cells continually produce one class of deep layer projection neuron. However, gliogenesis in the Dicer-null cerebral cortex was not delayed, despite the loss of multipotency and the failure of neuronal lineage progression.

conclusionsWe conclude that Dicer is required for regulating cortical stem cell multipotency with respect to neuronal diversity, without affecting the larger scale switch from neurogenesis to gliogenesis. The differences in phenotypes reported from different timings of Dicer deletion indicate that the molecular pathways regulating developmental transitions are notably dosage sensitive.
