Longevity in relation to total antioxidant status (a); total glutathione (b); malondialdehyde (c); and body mass (d). The slope of the solid line was extracted from the PGLS model presented in Table 1; the slope of the dashed line was extracted from PGLS model presented in Table 2. The slope of the dashed line in b was zero, as total glutathione was not included in the PGLS model presented in Table 2
