The number of studies does not correspond with the number of outcomes as some studies investigate multiple outcomes and several food items 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.
