Figure 1From: Associations of health, physical activity and weight status with motorised travel and transport carbon dioxide emissions: a cross-sectional, observational study Path analysis examining the contribution of active travel, motorised travel and engine size. Path 1 = indirect (mediated) path via active + motorised travel; path 2 = indirect path via motorised travel only; path 3 = indirect path via car engine size; path4 = direct path (‘unexplained’).Back to article page
