Bound water and pore water, each normalized to apparent bone volume, are not simply surrogates of one another (n=62, human femoral samples) as pore water weakly correlates with bound water with considerably scatter between the two water compartments. There are other factors besides matrix density that influence the amount of bound water in bone. Correlation coefficient (ρ) was determined using Spearman’s rank correlation (original data).
