Fig. 1From: A structural equation model to test a conceptual framework of oral health in Japanese edentulous patients with an item weighting method using factor score weights: a cross-sectional studyThe confirmatory factor analysis model to derive factor score weights. Bootstrap standardized direct effects for third-order hierarchical model of the Oral Health Impact Profile for edentulous subjects (OHIP-EDENT). Numbers on the upper right-hand side of the rectangles and ellipses represent the coefficient of determination associated with each structural equation. **P < 0.01, ***P < 0.001Back to article page
