2. Fig 1
The “box and whiskers” presentation of pectus index (PI), right ventricular end-diastolic (RVEDVI), end-systolic (RVESVI), and stroke (SVI) volume indices before (B) and after (A) surgery. The points indicate the geometric means, the boxes encompass the first and the third quartiles, and the whiskers encompass the range of the values.
