Relation between f_esc and O₃₂, with the average f_esc shown as black squares, in bins on log(O₃₂). The diamond points represent the high-confidence sample, and the dots show the parent sample. The dashed gray line shows the relation between f_esc and O₃₂ form Izotov et al. (2018a). The gray triangles indicate lower limits on the O₃₂ ratio for the points with S/N([O II]) < 3. Our points show no strong trend between ⟨f_esc⟩ and O₃₂.
