Table 3 Plasma markers of kidney function and urine markers of compliance, N = 159

From: Effect of glycemic index and carbohydrate intake on kidney function in healthy adults

  

Mean (95 % Confidence Interval) change from baseline by diet

  

High carbohydrate, high glycemic index diet

High carbohydrate, low glycemic index diet

Low carbohydrate, high glycemic index diet

Low carbohydrate, low glycemic index diet
