2. Appendix
Box-plots for 5 conditions.* The horizontal lines of the box represent the first, second, and third quartiles, with the diamond indicating the mean. The whiskers are drawn to the most extreme points in the group that lie within the fences, where the upper/lower fence is defined as the third/first quartile plus/minus 1.5 times the interquartile range. *Five conditions are: myocardial infarction (AMI), heart failure (HF), pneumonia (PN), chronic obstructive pulmonary disease (COPD), and total hip and knee arthroplasty. Heart failure and hip-knee showed the largest and smallest correlation coefficients. FPL = federal poverty level; HRRP = Hospital Readmission Reduction Program.
