2. Fig 1
Number of operations stratified by infection rate. The approximate means of the infection rate and the number of operations performed are indicated with vertical and horizontal dashed straight lines, respectively. The correlation between the number of operations and infection rate is −0.03 (p = 0.84). Simple linear regression gives the following equation: Infection rate = 1.62 − * (number of surgeries performed) (represented in the figure as the thick black line). The R2 for this equation is

3. Fig 2
Percentage of infections stratified to number of delayed sternal closures. The approximate mean of the infection rate is indicated with a horizontal dashed straight line. The correlation between the percentage of operations with a delayed sternal closure and infection rate is 0.05 (p = 0.76). Simple linear regression gives the following equation: Infection rate = * (percentage of delayed sternal closures) (represented in the figure as the thick black line). The R2 for this equation is
