Fig. 1. Partial correlations between blood HbA1c and the CV of starch intake (left) and between HbA1c and CV of diet glycemic index (GI; right) in 272 subjects with type 1 diabetes after adjusting for seven confounding variables (age, gender, duration of diabetes, insulin dose, height, weight and body mass index). Residuals are the differences between the observed values for HbA1c, CV starch and CV of diet GI and the values predicted from the confounding variables by multiple correlation analysis.
