Linear arrows show standardized regression weights. Curved arrows show correlations. Values above or under (variable fa12) the rectangles show squared multiple correlations (SMC, item reliabilities for fa1 to fa10, explained variance for variables fa11 and fa12). Variables fa11 and fa12 correspond to items fa12 and fa13 of the former version EORTC QLQ-FA13 in this orderBack to article page
