a
Values are adjusted mean (s.d.); s.d.=s.e. × sqrt (n), where s.e. is the standard error for the adjusted mean and n is the number of participants in that group (the rough n could be derived from Table 1). Analyses were adjusted for age, education and annual household income, where appropriate.
b
P for trend >0.05, all other P for trend <0.05.
