Table 5.
Rat animal and diet characteristics for intervention studies that compared LGI and HGI diets. The key information from each article using rats is shown. - denotes missing data. Approximate (~) starting weights are taken from graphs. Articles using two different strains or sexes are across two rows, with the defining characteristics in bold. Only new information is entered in the second row. Carb, carbohydrates; HGI, high glycaemic index; LGI, low glycaemic index; E, energy; n, sample size; SHR, spontaneously hypertensive rats; AL, amylose; M, male; SD, Sprague-Dawley; AP, amylopectin; F, female.
