(A) The flow diagram shows the design of the study. Subjects suitable for work were enrolled as part of the STePS study (19). Recurrence risk of syncope relapse was estimated within 5-year follow-up. 111 patients were lost after the 1st year of follow-up. The risk factors associated with syncope relapse at 6-month and 1-year follow-up were evaluated in all patients. (B) Bars summarize the occupational sector of active workers at the time of first syncope. Each bar indicates the number of workers employed in specific occupational sector. Gray shaded areas indicate the number of subjects who fainted while working and black lines indicate the number of syncope recurrences within 1 year from the first syncope event in each different group of active workers.
