†One occupational mechanical exposure at a time adjusted for body mass index, pack-years of smoking, leisure time shoulder intensive sports, diabetes mellitus, psychosocial strain, social support and region of residence.
‡The upper limits of the highest categories are shown for men/women.
§ Psychosocial factors were mutually adjusted and adjusted for upper arm elevation, body mass index, pack-years of smoking, leisure time shoulder intensive sports, diabetes mellitus and region of residence. No statistically significant associations were found between occupational psychosocial factors and surgery for SIS.
