Median survival times reported for mouse models of Tet deficiency. Median survival reported for models with germ line– or cell type–specific transgenes or gene deletions (top); median survival reported for inducible gene disruption or adoptive cell transfer models (bottom). For references, please refer to Table 1. For each Tet-deficient mouse model, the darkest color at the midpoint of each ribbon represents the approximate median survival. Note that the width and gradation of color do not necessarily reflect any statistical property.
