Fraction of sample showing spectra consistent with fully neutral IGM attenuation (blue points) and with absorption stronger than the neutral IGM, i.e. strong DLAs (orange points). While the fraction of strong DLA candidates drops slightly with redshift, the majority of z > 9 spectra are consistent with a neutral IGM.
