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

Immune molecules have been discovered recently to play critical roles in the development, function, and plasticity of the cerebral cortex. MHC class I (MHCI) molecules are expressed in the central nervous system and regulate activity-dependent refinement of visual projections during late postnatal development. They have also been implicated in neurodevelopmental diseases such as schizophrenia and autism. Despite the excitement generated by these unique roles for immune proteins in the brain, little is known about how these molecules regulate cortical connections. The first step toward elucidating the mechanism is to identify the spatial and temporal distribution of MHCI proteins throughout development. Using a pan-specific antibody that recognizes many MHCI variants for biochemistry and immunohistochemistry, we found that MHCI proteins are expressed in the rat visual cortex at all ages examined-during the peak of synaptogenesis, the critical period of synaptic refinement, and adulthood. Their abundance in the cortex peaked during early postnatal development, declining during periods of plasticity and adulthood. In contrast to current assumptions, pre- and postembedding immunogold electron microscopy (EM) revealed that MHCI proteins were present both pre- and postsynaptically at all ages examined. They were often found in the postsynaptic density and were closely associated with synaptic vesicles in the presynaptic terminal. These results suggest a previously undescribed model in which MHCI molecules function on both sides of the synapse to regulate connectivity in the mammalian visual cortex before, during, and after the establishment of connections.
