Integrin β1 is required for maintenance of vascular tone in postnatal mice.
Article in Journal of cell communication and signaling, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Connective tissue is required for maintaining the integrity of tissues. Integrins are the cell surface receptors responsible for cell attachment to extracellular matrix; however, their tissue-specific role in this process is poorly understood. Here, we test whether integrin β1 is required for blood vessel maintenance and integrity in adult mice. We show that adult mice containing a fibroblast/smooth muscle cell-specific deletion of integrin β1 exhibit impaired bleeding time and maintenance of vessel architecture, including progressively reduced levels of extracellular matrix (ECM). Vessels also possessed diminished levels of α-smooth muscle actin (α-SMA), and cells derived from vessels showed reduced production of mRNAs encoding ECM and α-SMA as well as reduced α-SMA protein and stress fibers and ECM contraction. Integrin β1 in adult fibroblasts/smooth muscle cells/pericytes is required for vasoconstriction and vascular maintenance.
