  1. First number in every cell – correlation coefficient; second number – the sample size. "Factor Analysis" cohort (first line in every cell) contains cases (69) when all four factors can be computed; Six other cohorts (second line in every cell) contain cases when at least two factors can be computed.
  2. ** Correlation is significant at the 0.01 level (2-tailed).
  3. * Correlation is significant at the 0.05 level (2-tailed).
