A Comparative Study of Smartphone Game with Spirometry for Pulmonary Function Assessment in Stroke Patients

Table 3

Concurrent validity measured with spirometry and smartphone-game application.

Parameters	ICC (2,1) 95%CI	95% LOA	CV ( %)
FVC - GA	0.91 (0.83-0.95)	75.35~142.22	19.34
FVC % - GA	0.92 (0.83-0.96)	74.22~140.03	19.03
FEV1 – GA	0.93 (0.86-0.96)	67.12~126.72	17.23
FEV1 % - GA	0.94 (0.89-0.97)	61.67~116.37	15.82

CV=coefficients of variation of method error; FVC=forced vital capacity; FEV₁=forced expiratory volume in 1 second; GA=game-based assessment; SG=smartphone game; ICC=intracorrelation coefficient; LOA=limits of agreement.
