Specific SFR vs. 12 + log(O/H) for our sample and including data from the literature (Hunt et al. 2012; Schruba et al. 2012; Filho et al. 2013; Bothwell et al. 2014). The metallicities for the ALLSMOG (Bothwell et al. 2014) sample have been modified as discussed in the text. As in Fig. 4, the open triangles for Schruba et al. (2012) correspond to their compilation of data from the literature and the filled ones to their metal-poor dwarf observations. The regression line is a robust best-fit of the Local Volume Legacy (LVL, Lee et al. 2009) and the dwarf irregulars from Lee et al. (2006). The various colors for the LVL give the Hubble type (early types red, magenta; late types blue, cyan).
