Longitudinal Changes in Porosity Parameters Calculated Using Standard and Baseline Mapping Techniques at the Distal Radius (All Participants Pooled, n = 37)

Parameter Relative change
without baseline
mapping (%)		 Relative change
with baseline
mapping (%)		 p Value
Ct.Th −2.94 ± 4.53 1.17 ± 6.22 0.002
Ct.Po.V 10.32 ± 32.64 14.84 ± 32.54 0.10
Ct.Po 12.88 ± 32.52 18.09 ± 40.72 0.48
Po.Dm 3.87 ± 9.77 6.15 ± 9.67 0.13
Po.Dm.SD 5.00 ± 19.79 11.63 ± 22.34 0.08

Ct.Th = cortical thickness (mm); Ct.Po.V = cortical pore volume (mm3); Ct.Po = cortical porosity (unitless ratio); Po.Dm = mean cortical pore diameter (mm); Po.Dm.SD = SD of mean cortical pore diameter (mm).

The p value represents difference between relative change calculations.
