Table 4 Results for total number of symptoms and symptom distress indices when fitting linear mixed models to transformed sclaes

From: The impact of antiretroviral therapy on symptom burden among HIV outpatients with low CD4 count in rural Uganda: nested longitudinal cohort study

Parameter Square root of total Number of Symptoms Square root of Global Distress Score Square root of Physical Symptom Distress Score Square root of Psychological Symptom Distress Score
Constant 3.5 (3.4; 3.7) 1.1 (1.0; 1.1) 1 (0.9; 1.0) 0.8 (0.7; 0.9)
Days/100 −0.9 (−1.3; −0.6) −0.4 (−0.5; −0.3)
(Days/100)2 0.2 (0.04; 0.3) 0.1 (0.02; 0.1)
√(Days/100) −0.3 (−0.4; −0.2) −0.3 (−0.4; −0.2)
σu (Between subjects) 0.5 (0.4: 0.7) 0.1 (0.06; 0.3) 0.1 (0.1; 0.2) 0.2 (0.2; 0.4)
σe(Within subjects) 0.7 (0.6; 0.8) 0.4 (0.3; 0.4) 0.3 (0.3; 0.4) 0.5 (0.4; 0.5)
  1. Note that each cell contains the parameter estimate together with 95% confidence limits where appropriate (i.e. if the given parameter is included in the model)
