Porosity and pore size of the scaffolds with different percentages of PEO removal which were determined using two methods: Liquid displacement method and Apparent porosity (*p ≤ 0.05 for scaffolds prepared using different concentration of PEO)

PEO %	Porosity measured by liquid displacement (%)	Apparent porosity (%)	Pore size (µm)
