Relationship between numbers of chronic conditions and hospitalizations (1A) and between numbers of chronic conditions and bed days (1B).
(1A) The black line indicates the observed number of hospitalizations by the number of chronic conditions. The red line indicates the reference regression line that shows the mean number of hospitalizations multiplied by the number of chronic conditions. (1B) The black line indicates the observed number of bed days by number of chronic conditions. The red line indicates the reference regression line that shows the mean number of bed days multiplied by the numbers of chronic conditions.

Black line, no education; red line, short education; green line, medium education; blue line, long education.
