Supplementary Table 1: Quantification of bone mineral density and bone microarchitecture parameters in the patient with Hajdu-Cheney syndrome (HCS) in 2014 and 2020.
BMD: bone mineral density, BV/TV: bone volume/tissue volume, Tb.N: trabecular number, Tb.Th: trabecular thickness, Ct.Th: cortical thickness. %: % change. % mean is compared to age- and sex-matched reference values (Burt LA, Liang Z, Sajobi TT, Hanley DA, Boyd SK (2016) Sex- and Site-Specific Normative Data Curves for HR-pQCT. J Bone Miner Res 31:2041-2047).
