a A Scatter plot of arterial inflow vs optic nerve sheath diameter (ONSD) showing a moderate positive correlation (r = 0.58, p < 0.0001) suggesting higher arterial inflow increases ICP. b A Scatter plot of the percentage sagittal sinus (SSS) return vs optic nerve sheath diameter (ONSD) with a weak negative correlation (r = − 0.35, p = 0.02) suggesting a reduced venous return correlates with an elevation in ICP. c A Scatter plot of body mass index (BMI) vs optic nerve sheath diameter (ONSD) showing no overall correlation. d A Scatter plot of Age vs body mass index (BMI) showing a moderate positive correlation (r = 0.47, p = 0.002) suggesting an increase in obesity related venous pressure may become more important with age
