Compositional means of the measured worktime per day with forward bending of the back >30° (Composition A) and >60° (Composition B) among workers without (N=740) and with (N=204) an event of long-term sickness absence (LTSA) and among the total population (N=944).

^a% represents that these exposures of the worktime composition are presented as the proportion of total measured worktime per day (table 1).

^bNon-upright position includes sit and lie postures.
