The groups received similar volumes of enteral nutrition solution -LSB- @ mL/d ( @ % CI : @ , @ mL/d ) compared with @ mL/d ( @ % CI : @ , @ mL/d ) ; P = @ -RSB- , which led to a @ % increase in daily calories in the group given the @-kcal / mL solution -LSB- @ kcal/d ( @ % CI : @ , @ kcal/d ) compared with @ kcal/d ( @ % CI : @ , @ kcal/d ) ; P < @ -RSB- .
