Pereira 2002 | No lipid or blood pressure outcomes. The primary outcomes of this study relate to insulin sensitivity.

Pins 2002 | Excluded due to a lack of clarity about the relative macronutrient content of the diets. There is a reference to the macronutrient data in the paper (Table reference T2) to the journal website. However, the data were not available there, so we attempted to contact the authors, but were unable to find up‐to‐date contact details. In the original version of this review this study was included as it aimed for the same macronutrient content in both arms. It was marked as awaiting further information. We have been unable to verify the relative macronutrient of the diets (as above), so the study is now excluded. |
