		Smoker n=35				Non-smoker n=39			Stopped smoking n=15
		Mean	SEM			Mean	SEM		Mean	SEM
Age	41.40	1.76		44.67	2.06		43.33	2.76
Exposure (y)	13.37	1.21		16.56	1.47		16.93	2.68
Time from 1st to 2nd test (months)	31.52	3.62		33.28	4.97		30.88	4.66
Interval between 2nd and 3rd tests	9.42	0.91		7.74	1.17		11.70	2.97
FSBP%_BL	35.04	6.51		40.86	6.21		38.07	10.24
Δ FSBP_BL-FT%	14.37	5.77		32.91	6.45		25.04	12.59
FSBP%^7-160	49.24	6.30		73.76	4.15		63.11	10.29
Δ FSBP%	10.69	5.01		5.98	6.24		18.07	7.57
FSBP% <30	17 (48.58%)			6 (15.38%)			5 (33.33%)
FSBP%⩾30^7-150	78.67	3.47		71.66	3.76		74.59	6.23

FSBP%_BL is the FSBP% at baseline.
Δ FSBP_BL-FT is the change in FSBP from the baseline test to the third test.
FSBP% and ΔFSBP% refer to the third test and the change from the second to the third test.
↵7-150 p<0.05;
↵7-160 p<0.005 by Fisher's exact test.
