Results
The hand X-rays from 49 girls (4.15-15.33 years old) and 30 boys (3.32-15.16 years old) were included in the study.
BoneXpert couldn't analyze the hand X-ray from a girl with Rett’s syndrome due to severe finger contractions (Fig. 2).
In another child,
the BHI was not calculated because of a short fourth metacarpal bone (Fig. 3).
The manual GP versus BoneXpert GP scores are statistically analyzed and presented (Fig. 4).
- No statistically significant difference was found between manual GP (experienced examiner) scores and BoneXpert GP scores (Fig. 4: Table 2,
Fig 3.1).
- In contrast,
a statistically significant difference was found between manual GP (inexperienced examiner) scores and BoneXpert GP scores (Fig. 4 : Table 2).
- Of note,
subgroup analysis revealed statistically significant differences for all comparisons,
only in the female group.
This finding should be investigated further (Fig. 4 : Table 3).
Six girls (12% of the female patients) and 3 boys (10% of the male subjects) had a BHI-SDS lower than -2.
Some of them had further laboratory tests which revealed vitamin D deficiency (<50 nmol/L).
The automated procedure using BoneXpert lasted for a few seconds,
contrary to the manual approach,
which was more time consuming (2-3 minutes).
