Table 4 The comparison of total and trabecular bone volumes and the ratio of trabecular volume versus total volume for the lumbar vertebrae of the control and heparinized rats.

From: Is decreased bone mineral density associated with development of scoliosis? A bipedal osteopenic rat model

  Heparin Control P value (t-test)
Total Volume (mm3 ± StDev) 21.63 ± 2.22 27.74 ± 2.39 0.001
Trabecular Volume (mm3 ± StDev) 9.71 ± 0.67 15.96 ± 0.91 < 0.001
TrabV/TotV Ratio (% ± StDev) 45 ± 2.5 57.9 ± 6.2 0.002
  1. Heparinized group demonstrated significantly low total and trabecular bone volumes. Note that trabecular to total volume ratio for heparinized rats is also significantly low compared to control animals.
