Details

This network meta-analysis is reported by Hooper et al. (2000) to assess the effects of change in dietary fats on cardiovascular mortality. Treatment 1 is a control diet and treatment 2 is a reduced fat diet. Originally, study 2 compares three treatments, which include treatments 1 and 2, and another diet. Here, we treat these two different types of diet as the same treatment, but keep the treatment arms separate.
