  1. *These sample sizes correspond to the main sample from Veroia. Computations on test-retest and interrater reliability have been based on N = 100 and N = 50, respectively.
  2. † These Pearson correlation coefficients have been corrected for item-scale overlap. Correlations for basic scales have been mainly computed for N = 205, that is after deleting missing observations listwise. However, any calculation regarding the radiographic-laboratory scales and items has been based on a smaller sample that was available (N = 43).
