Physical activity for antenatal and postnatal depression in women attempting to quit smoking: randomised controlled trial

Table 2 Comparison^a of depression scores in two trial groups at end-of-pregnancy and six months after birth (N = 784^d)

Visit time	EPDS score N, Mean (SD)		β (difference between PA and usual care, basic adjustment^b) (95% CI)	β (difference between PA and usual care group, fully adjusted^c) (95% CI)
Visit time	Usual care group	Physical activity group
baseline	393, 7.7 (5.0)	391, 7.6 (5.3)
End of pregnancy	194, 7.2 (5.0)	189, 8.0 (4.9)	1.06 (0.19, 1.94) p = 0.017	0.95 (0.08, 1.83) p = 0.033
6 months follow-up	133, 6.6 (4.7)	146, 6.8 (4.8)	0.52 (−0.45, 1.50), p = 0.293	0.37 (−0.59, 1.33) p = 0.450
