Table 4 shows the overall data for responses to the gastrointestinal distress questionnaire, with particular attention given to responses rated moderate to severe.

Numbers in brackets represent data expressed as a percentage of maximum number of responses. P, Placebo; MD, maltodextrin beverage; MD + F, maltodextrin-fructose beverage. *denotes a significant difference to other test conditions (P < 0.05).
