Brant et al., 23	Enteral feeding via gastrostomy, with a mean monitoring period of 5.9 months.
Caselli et al., 24	Enteral feeding via gastrostomy (n=25) and oral feeding (n=29).
García-Contreras et al., 25	Enteral feeding via nasogastric tube (n=8) and gastrostomy (n=5) for 4 weeks. Use of a lactose-free infant formula (Nestlé®), adding corn syrup to the formula to increase the energy density.
Kibirige 26	Oral feeding for 8 weeks. 4 children received liquid nutrition and supplementation.
Leal-Martínez et al., 12	Oral feeding. Use of 3 liquid diets, 2 administered at breakfast and 1 at dinner. Follow-up group (FG) (n=10): normal diet. Control group (CG) (n=10): vermifugated and received a nutritional therapy recommended by the WHO (2010). Intervention group (IG) (n=10): vermifugated and received the Nutritional Support System (NSS).
Sanders et al., 27	Enteral feeding via nasogastric tube (n=4) and gastrostomy (47) for 6 months. The dietary formulas used were Complete Modified Formulas (Sandoz) or lsocal (Mead Johnson), each one providing 1 kcal/mL.
Savage et al., 28	Enteral feeding by nasogastric tube (n=1) and percutaneous endoscopic gastrostomy (n=12). Standard enteral formula based on casein and another with 50% whey and 50% total casein protein for 1 week (n=7), and a formula based on partially hydrolyzed whey protein (n=6).
Schoendorfer et al., 31	Children with CP (case group): percutaneous (n=9) and oral (12) enteral feeding.
Schoendorfer et al., 13	Enteral (n=9) and oral (n=15) feeding.
Soylu et al., 14	Oral feeding for 6 months.
Sullivan et al., 29	Enteral feeding by gastrostomy for 12 months.
Vernon-Roberts et al., 30	Enteral feeding by gastrostomy for 6 months. An enteral feeding of low caloric energy (Kcal), complete with micronutrients and rich in fiber, was administered.
