Whole-Body Bone Mineral Content (BMC), Lumbar Spine BMC, and Lumbar Spine Bone Mineral Density (BMD) of Infant Groups Over Time
REGRESSION
Data are reported as means with SDs and were analyzed using a linear mixed-effects regression model for group-by-time interaction and time; the model included participant-level random intercepts and slopes for time. Post hoc testing showed no significant differences between trial groups over time adjusted for multiple comparisons except for time, which was significant for all comparisons. A total of 469 whole-body scans and 484 lumbar spine scans were obtained of a possible 489 across all time points. The remaining were not obtained or analyzed due to movement artifacts. The shaded areas correspond to the reference group SDs.Serum 25(OH)D
