Patient level analyses (n=192) on absenteeism in intervention and control groups

Total (n=192)
Intervention group (n=109)Control group (n=83)p value
Time to return to work: period between onset of sickness leave and first return to work (most of the time partial).
Time to full return to work: period between onset of sickness leave and full return to work.
Duration of sickness leave: number of days lost until full return to work with a correction for partial return.
Time to recurrence: period between full return to work and recurrence of sick leave for any reason.
Incidence of recurrence: number of recurrences in a period until 12 months from full return to work.
p value from multivariate (Cox) analyses with age and hours of appointment as covariates.
