Stellar mass-SFR relation of LGRB hosts (symbols) compared to that taken from the models of Boissier et al. (2010) for SFGs shown as a set of curves (solid at redshift 0, dashed at redshift 1.1, dotted for intermediate redshifts). The shaded area corresponds to our completeness limits. The dashed lines within this area are the two regression lines (for the SFR as a function of the stellar mass and the stellar mass as a function of the SFR) computed from the LGRB hosts data.
