The value of significant (P _bonf < .002) correlations were interpreted as being low when Pearson, Spearman, or point-biserial correlations between FCEs with ICF factors are ≤ 0.25 and fair when 0.25 < Pearson, Spearman, or point-biserial correlations ≤ 0.50 [14]; DOT, Level of physical workloads according to the Dictionary of Occupational Titles [35]; H hypothesis, ICF International Classification of Functioning, Disability and Health.
