Change in work characteristics, health, and health related behaviours for respondents by employment status

Fixed termp value for differenceFixed term to permanentp value for differenceTest of heterogeneity of differences
Figures (adjusted for age, sex, and income) are differences in means (95% CI) and p values for differences at follow up and p values of analyses of variance for repeated measures for tests of heterogeneity of differences (in all cases the mean difference for permanent employment was set to 0.00). Tests of heterogeneity for employment status group differences between baseline and follow up were tested using the repeated measures analyses of variance procedure to determine the interaction between time and employment status.
