  1. Ca.TV ‒ total volume of canaliculi (mm3) LCN.TV ‒ total volume of the LCN (mm3).
  2. Ca.TV/BV ‒ porosity of canaliculi (%) LCN.TV/BV ‒ porosity of the LCN (%).
  3. Ca.V ‒ average volume of canaliculi per cell (µm3) Ca.V/Cell.V ‒ local porosity of canaliculi.
  4. Ca.V/Lc.V ‒ ratio between the average volume of canaliculi and lacuna per cell (%).
  5. *p-value < 0.05.
