2nd, secondary; On.N/T.Ar, secondary osteon population density (‘OPD’); On.B/T.Ar, area of secondary bone expressed as a percentage ([On.B/T.Ar] × 100).

Means and (standard deviations) are shown for N.On/T.Ar and On.B/T.Ar; these parameters were determined using methods described by Skedros et al. (2009), Skedros et al. (2011).
