||P.7 right column 4th paragraph: "The change in ventricular volume depending on the hydration status may now be compared with observations in diseases.
Dehydration would only have a negligible effect in schizophrenia and multiple sclerosis in view of reported average ventricular increases by 26% [primary source 31] or 20–26% [primary sources 32, 33], respectively."
