Zavarygin et al. (2018) compiled a list of 15 deuterium abundance measurements, discarded two because the remaining 13 measurements are then consistent with gaussianity, and found that the weighted mean baryon density (Omega_b h^2) determined from the 13 measurements is mildly discrepant (1.6sigma) with that determined from the Planck 2015 cosmic microwave background anisotropy data in a flat cosmogony. We find that a median statistic central estimate of Omega_b h^2 from all 15 deuterium abundance measurements is a more accurate estimate, is very consistent with Omega_b h^2 estimated from Planck 2015 data in a flat cosmogony, but is about 2sigma lower than that found in a closed cosmogonical model from the Planck 2015 data.
