Table 2 Hazard ratios from multivariable Cox regression model for the association of time-to-assessment with age, sex, fatigue, disability, anxiety, depression, and severity (school attendance) (N = 246).

From: What stops children with a chronic illness accessing health care: a mixed methods study in children with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME)

  Hazard ratio (95% CI) P-value
Age 0.96 (0.88, 1.04) 0.33
Sex (female vs male) 0.91 (0.68, 1.23) 0.55
Fatigue (Chalder) Score* 1.15 (1.03, 1.29) 0.01
Disability (SF-36)* 0.98 (0.87, 1.12) 0.79
Anxiety (HADS)* 0.97 (0.90, 1.05) 0.45
Depression (HADS)* 1.00 (0.92, 1.09) 0.94
Number of symptoms 0.94 (0.88, 1.01) 0.08
Severity of illness   0.62 (Ptrend)
   Mild 1.00 (reference)  
   Moderate 1.04 (0.74, 1.45) 0.82
   Severe 1.11 (0.73, 1.67) 0.62
  1. * These measures were re-scaled so that the range for each was approximately 0-10 to facilitate comparability in the multivariable model.
