Baseline matched comparison among 
Patients with oral nutrition support (ONS group) and nasogastric tube feeding (TNF group) were included in other two clinical trials conducted in our center during the same period (NCT02403531 and NCT02969473). The matching was based on 1:1:1 matching within a prespecified caliper width without replacement (Figure Flow diagram for this study. NTF, nasogastric tube feeding; ONS, oral nutritional supplements; PEG, percutaneous endoscopic gastrostomy.For NTF and ONS groups, supplements were prescribed to meet estimated nutritional needs (30–35 kcal/kg of energy, 1.0–1.5 g/kg of protein, and electrolyte supplementation each day).
