= grayed cells indicate statistically significant differences (p ≤ 0.05) between large and small osteons in the same column and within the bone type.
†
Small osteons in this column are based on the mean diameter in each bone type; a 200μm cutoff is also shown for the ribs.
†
Large osteons are defined as greater than the mean diameter of the osteons in each bone type.
