  1. Pearson’s intercorrelations for the Nijmegen Clinical Screening Instrument (NCSI) and Short Form 36 (SF-36) for Q-fever patients at 12 months after onset of illness. N = 3091, p < .01 for all intercorrelations. Intercorrelations ≥ .70 are in italics.
  2. 1) N varies between 302 and 309 for individual intercorrelations, due to missing values within some of the questionnaires.
