  • The number of studies does not correspond with the number of outcomes as some studies investigate multiple outcomes and several dietary patterns in the same population.

  • CR, cancer recurrence; CSM, cancer-specific mortality; DO, death from other causes than cancer; HL, Hodgkin’s lymphoma; MM, malignant melanoma; NHL, non-Hodgkin’s lymphoma; OM, overall mortality.
