At the baseline.
Secondary outcome [1] 265438 0
Blood samples from fasting volunteers was collected through the brachial venipuncture.
Timepoint [1] 265438 0
At baseline.
Secondary outcome [2] 265439 0
Functional capacity was evaluated by the index of work ability (WAI), which iis composed of 60 questions. The answers are converted into numerical values and then weighted. The results can range from 7 (low work capacity) to 49 points (optimal capacity of the work).
Timepoint [2] 265439 0
At baseline.
