Z-scores are normalized to age- and sex-matched controls; scores higher than −2.0 are within the expected range.13 T-scores are normalized to young sex-matched controls; scores from −1 to −2.5 are considered osteopenic and values below −2.5 are considered osteoporotic.13
Only patients with usable data at both time points were included.
