Tunneling-nanotube development in astrocytes depends on p53 activation.
Article in Cell death and differentiation, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 233 papers, 1 of them a synthesis that pooled 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.
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
Tunneling nanotubes (TNTs) can be induced in rat hippocampal astrocytes and neurons with H(2)O(2) or serum depletion. Major cytoskeletal component of TNTs is F-actin. TNTs transfer endoplasmic reticulum, mitochondria, Golgi, endosome and intracellular as well as extracellular amyloid β. TNT development is a property of cells under stress. When two populations of cells are co-cultured, it is the stressed cells that always develop TNTs toward the unstressed cells. p53 is crucial for TNT development. When p53 function is deleted by either dominant negative construct or siRNAs, TNT development is inhibited. In addition, we find that among the genes activated by p53, epidermal growth factor receptor is also important to TNT development. Akt, phosphoinositide 3-kinase and mTOR are involved in TNT induction. Our data suggest that TNTs might be a mechanism for cells to respond to harmful signals and transfer cellular substances or energy to another cell under stress.
