Table 2 Knowledge of risks and of smoking cessation, by self-reported assessment of tobacco smoking

	Provider assesses 100% of women (n = 96)	Provider assesses fewer than 100% of women (n = 26)

Knowledge of risk
Smoking during pregnancy increases the risk of:
Miscarriage (losing the baby)	90 (94)	21 (81)	0.055
Low birth weight of baby	96 (100)	24 (92)	0.044
Breathing problems and sickness in infant	93 (97)	25 (96)	1.000
Mother having high blood pressure and increased heart rate (pre-eclampsia)^b	3 (3)	1 (4)	1.000

Knowledge of cessation
Nicotine replacement therapy (patches, gum etc) can help women quit	85 (89)	20 (77)	0.197
Nicotine replacement therapy shouldn't be used in pregnancy	71 (74)	11 (42)	0.004

Total knowledge of smoking cessation score (median(Q1, Q3))	2 (2, 3)	2 (1, 2)	0.010

^aFisher's exact test, except for knowledge scores which used the non-parametric Mann-Whitney test
