Figure 3.

Meta-analysis of the extracted results for measures of glucose homeostasis in high versus low glycaemic index fed animals. A plot of the calculated effect size and sampling variance for each of the four traits either as a whole or broken down by confounding factor: (a) Fasting Glucose; All, Length of Diet, Dietary Fat and Fasting Time n = 30, Mice n = 16, Rats n = 14, Female n = 4, Male n = 26, Starting Age n = 27, No Anaesthesia n = 17, Anaesthesia n = 13; (b) Fasting Insulin; All, Length of Diet, Dietary Fat and Fasting Time n = 25, Mice n = 9, Rats n = 16, Female n = 3, Male n = 22, Starting Age, n = 23, No Anaesthesia n = 12, Anaesthesia n = 13; (c) Glucose AUC; All, Length of Diet, Dietary Fat and Fasting Time n = 18, Mice n = 9, Rats n = 9, Female n = 1, Male n = 17, Starting Age n = 17; and (d) Insulin AUC; All, Length of Diet, Dietary Fat and Fasting Time n = 16, Mice n = 2, Rats n = 14, Female n = 2, Male n = 14, Starting Age n = 14. AUC, area under the curve; n, number of effect sizes; df, degrees of freedom; E, energy. **** p < 0.0001
