Subsets were defined based on three factors: sex (male, female), diet (HP-NB, higher-protein nut bar; HC-CB, higher-carbohydrate cereal bar), and glycaemic status (N, normoglycaemia; P, prediabetes). The table presents the results for all possible combinations of factors, including overall effect, effect within each sex level, diet level, and glycaemia level, and effect within each glycaemia level when stratified by diet. Significant p-values (p < 0.05) are shown in bold type.
