  1. SD standard deviation, CI confidence interval.
  2. Positive z-scores indicate better outcomes in AML LTS compared to the reference cohort, and negative z-scores indicate inferior outcomes in AML LTS vs. the reference Consequently, higher z-scores indicating less symptom burden.
  3. aSkewness of the underlying distribution below –2.0.
  4. bp values correspond to non-parametric Wilcoxon test and might result in inconsistent results compared to symmetric 95%CI presented in the neighboring column.
