Table 6.

Spirometry results in percentage of predicted values.

	Controls	AMMU
	(n = 39)	All (n = 47)	Metal (n = 31)	Titanium (n = 16)
Spirometry
FEV1/FVC (% pred.)	79 (66–93)	80 (66–94)	79 (66–94)	81 (72–88)
FEV1 (% pred.)	88 (62–122)	93 (74–113)	92 (75–113)	93 (74–107)
FVC (% pred.)	89 (67–118)	92 (71–107)	92 (75–107)	91 (71–104)

Values are geometric mean (minimum–maximum).

FEV1, forced expiratory volume in one second; FVC, forced vital capacity.

Reference values for healthy individuals are 80%−120%.
