  1. Not all patients answered every question. Therefore, 159 of the 194 patients were included in the multivariate analyses. Age and gender were controlled for in the multivariate analyses.
  2. 1Univariate variables P < 0.20, age and gender are shown.
  3. 2Multivariable analysis, in P < 0.20, out P < 0.05.
  4. 3Educational status: low = 0, high = 1.
  5. 4Employment status before ICU stay: employed = 0, unemployed = 1.
  6. 5Personality trait: pessimism = low score; optimism = high score.
  7. CI, confidence interval; OR, odds ratio.
