Overview

Commentary finds flawed statistics may mislead clinical guidelines on cannabis use during immunotherapy in cancer care.

Key Points

  • Cannabis use correlates with poor clinical outcomes in immunotherapy, indicating potential adverse effects.
  • The original study faced serious statistical issues, including unverifiable non-parametric statistics and errors in arithmetic.
  • Comments highlighted flaws in reporting methods, like switching from two-tailed to one-tailed tests and not considering key confounds.
  • Errors may misguide treatment decisions for cancer patients needing pain and anti-nausea care during treatment.
