Identification of ATP8B1 as a blood-brain barrier-enriched protein.
Article in Cellular and molecular neurobiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
In order to define the molecular anatomy of the blood-brain barrier (BBB) that may be relevant to either barrier or transport function, proteins that are overexpressed in the cerebral microvessels should be identified. We used differential display to identify novel proteins that are overexpressed or unique to the BBB. DNA sequence analysis is one of the differentially expressed transcripts showed that it is highly homologous with the ATPase class I, type 8B, and member 1 (ATP8B1) protein and contains an ATPase domain and a phospholipid-binding domain. ATP8B1 is expressed in the BBB microvessels but not brain tissue lacking microvessels. Likewise, ATP8B1 was enriched in BBB microvessels similar to glucose transporter 1. Immunohistochemistry using an ATP8B1-specific antibody demonstrated preferential staining of the microvessels within the cerebral tissue. These results suggest that ATP8B1, a P-type aminophospholipid translocase, is enriched in cerebral microvessels and may have a role in plasma membrane lipid transport.
