Comparison of the differences in pulmonary function between the two groups

Variables	AB${}^{\text{a}}$	RCS${}^{\text{b}}$	$t$ value	$P^{\ast }$
Pulmonary function
FVC(%)${}_{\text{Predicted}}$	3.43 $\pm$ 4.23	19.57 $\pm$ 11.50	3.480	0.009
FEV${}_1$(%)${}_{\text{Predicted}}$	5.00 $\pm$ 6.78	14.29 $\pm$ 7.86	3.980	0.036

${}^{*}$independent $t$-test was significant at $P<$ 0.05. Data are mean $\pm$ standard deviation. ${}^{\text{a}}$AB: Abdominal breathing. ${}^{\text{b}}$RCS: Respiratory and core-postural stabilisation.
