Table 1 Physical and mental component summary scores using the norm-based scoring algorithm with orthogonal rotation

From: Reanalysis of the physical and mental health summary scores of dialysis versus conservative care in older patients with advanced chronic kidney disease: a critical appraisal

  Not yet started on dialysis (n = 39) Started on dialysis (n = 34) Conservative care (n = 23) P value (Tukey HSD)
Physical component summary score, mean (SD)a 38.3 (10.4) 34.2 (9.3) 30.9 (7.2) 1: < 0.01b
2: 0.38c
3: 0.16d
Mental component summary score, mean (SD)a 52.8 (9.6) 50.5 (12.7) 47.5 (11.2) 1: 0.17
2: 0.58
3: 0.65

  2. aScores range between 0 and 100; higher scores indicate better health-related quality of life
