Association of Intraoperative Transesophageal Echocardiography and Clinical Outcomes After Open Cardiac Valve or Proximal Aortic Surgery

Figure 1.. Surgeons’ Overall Preference for TEE This histogram plots the overall distribution of surgeons’ preference (probability intraoperative TEE use by surgeon). The blue lines demarcate surgeons with equivocal preference for intraoperative TEE (eg, surgeons with probability of TEE use between 0.30 and 0.70).

Figure 2.. Study Participant Flow Diagram Overview of the study design. The left panels illustrate the all-patient, across-hospital, across-surgeon matched comparison. The right panels illustrate the within-hospital, within-surgeon (with equivocal TEE preference: TEE 0.30–0.70) matched comparison.
