Registry-based approach used to estimate giant cell tumor (GCT) of bone incidence and incidence rates in 2017.

Country	2017 Population	GCT Incidence	GCT Incidence Rate per Million
China	1,409,517,397	2094*	1.49*
Japan	127,484,451	160	1.25
US	324,459,468	447	1.38

^⁎3625 new cases in 2017 or 2.57 per million accounting for proportionally higher incidence of GCT in China per Guo et al [9].
