Variation in the ISM Na I D resonant line profile as a function of the SFR for the galaxies with log(M)_⋆ >  10.7 M_⊙ and log(SFR) > 0.0 M_⊙ yr⁻¹ in the total sample (top panel), in pure SF galaxies (middle panel) and in AGN dominated objects (bottom panel). The intensity of the line increases with increasing SFR, from the magenta to the blue curves. Only galaxies with SFR ≥ 12 M_⊙ yr⁻¹ show a blue-shifted Na I D line, detected with a significance > 3σ. The pure SF and AGN subsamples show the same trend observed in the total sample.
