Table 2.
Descriptive summary of histology data sub-divided by estimated sex and age-at-death groups. SD standard deviation, MAX. maximum, MIN. minimum, V.Po density of canals/pores per mm2, H.Ar/On.Ar ratio of Haversian canal to osteon area in µm2, OPD osteon population density per mm2, Ct.W_RI robusticity index (RI) calculated using cortical width (Ct.W) data, Circ_RI robusticity index (RI) calculated using midshaft circumference (Circ). All variables are unitless.
