CDFs of the gas-phase oxygen abundances (12+﹩\mathrm{log}({\rm{O}}/{\rm{H}})﹩) for LFBOT hosts (blue), LGRBs (yellow), SNe II (purple dashed line), SNe Ibc (orange dotted line), SNe Ibn (green), SLSNe-I (pink), and a field galaxy population from SDSS (black). LFBOT hosts are clearly more metal-rich than SLSNe-I and LGRB hosts and more metal-poor than SNe Ibc and II hosts. In addition, LFBOTs trace lower metallicities than the field galaxy population.
