| OI total | OI type III | OI type IV | p (III versus IV) | |
|---|---|---|---|---|
| n (female/male) | 41 (28/13) | 13 (11/2) | 28 (17/11) | 0.126 a |
| Age (mean ± SD; years) | 19.0 ± 7.4 | 20.6 ± 8.6 | 18.2 ± 6.8 | 0.333 b |
| Height Z‐score (mean ± SD) | −5.2 ± 3.3 | −8.8 ± 2.4 | −3.6 ± 2.1 | <0.001 b |
| Weight Z‐score (mean ± SD) | −1.3 ± 1.5 | −2.5 ± 0.9 | −0.8 ± 1.4 | <0.001 b |
a
The p value was calculated using chi‐square test.
b
The p value was calculated using unpaired t test for normally distributed data.
Height/weight correlation coefficient r = 0.755.
