A correlation between SN II metal line strength and host HII region
  oxygen abundance
  Dessart et al., demonstrated that type II supernova (SN II) model spectra
present increasing metal line strength with increasing progenitor metallicity.
To confront these models with observations, we obtained a large sample of SN II
host HII region emission line spectroscopy. We show that inferred SN II host
HII region metallicities have a statistically significant correlation with the
strength of SN II metal lines, specifically FeII 5018A.
