Models were stratified by active versus retired work status and by years employed before the baseline survey (< 5 and ≥ 5 years).
FEV1 level increased significantly with years since cessation of exposure, which suggests that active versus retired work status might be an important confounder or effect modifier of endotoxin exposure.
Secondary outcome variables were: average pain during the past week, the Fear Avoidance Beliefs Questionnaire, participant satisfaction with treatment, active range of motion, work status and clinical shoulder tests.
All models for FEV1 level and symptoms were adjusted for age (year), height (centimeters), sex (female as reference), smoking status (current or former smoker with never smoker as reference), work status (active vs. retired) and years since cessation of exposure.
First, to calculate the percentage of health professionals that will have left practice before the target year, i.e. Element 8 of the model, information is required about the age, career ambition and work status (active or not) of health professionals.
Variables related to history that were examined in relation to disability were medication use (yes/no), symptom duration, work status (having an active work-related claim), and smoking habits (yes/no).
In all other models patients in different work situations were included, and the variables "work status" (recoded as "potentially active" and "other") and "sick leave" ("yes" or "no") were included.
Of the 2626 POIS participants who were workforce-active pre-injury, 11 were missing responses to the work status question at the 3 month post-injury survey and were excluded from this investigation.
All the respondents (except five), independently of their gender, age, or work status, mentioned the interruption to daily activities (i.e., whether they were professionally active or not, and whether they had an independent or dependent work status).
For the outcome on work status we present the results in terms of active status (job, part or full time) versus passive status (sick leave, rehabilitation or disability pension).
Work status was associated with the use of a generic drug for five active ingredients (furosemide, bisoprolol and thiazides, claritromycin, tramadol and acetylcysteine) but with opposite results.
