4. Barriers to vaccination	1.27 (0.11 to 2.44)	−1.55 (−2.34 to −0.80)†	0.001
5. Benefits of vaccination	−0.05 (0.00 to 1.78)	2.56 (2.13 to 3.00)	<0.001
6. Cues to vaccination
HSCT team understands my condition	1.14 (0.55 to 1.32)	1.63 (1.52 to 1.75)	<0.001
GP understands my condition	−0.32 (0.83 to 0.13)	0.59 (0.55 to 0.83)‡	<0.001
7. Worry
About catching influenza	0.14 (−0.43 to 0.71)	0.39 (0.17 to −0.63)	0.34
Less about catching influenza if vaccinated	−0.23 (0.60 to 0.07)	0.80 (0.61 to 1.00)	<0.001
8. Self-efficacy
Have enough information to decide about vaccination	0.14 (−0.32 to 0.58)	0.81 (0.61 to 1.00)	0.007
Would find it easy to attend GP for vaccination	0.32 (−0.12 to 1.72)	1.10 (1.89 to 2.00)	<0.001
9. Anticipated regret
Of catching influenza if not vaccinated	0.27 (−0.21 to 0.74)	1.35 (1.18 to 1.52)	<0.001
