Fig 4. Distribution of ACE-27 categories in different age groups.

Distribution of ACE-27 score of none, mild, moderate and severe comorbidities among four age groups in all 194 AML patients. 22 patients were younger than 41 years, 53 patients were between 41 and 59 years old, 119 patients were more than 60 and 58 patients more than 70 years old. Increasing age was significantly associated with higher ACE-27 score as analyzed by x² test (p < .000).
