Table 3. Results of the binary logistic regression, used to identify the possibility of PFO, indicating that the factors influencing the possibility of PFO opening are P-plateau >26 with an OR of 3.42 and RV≥LV with an OR of 3.13.

PFO: patent foramen ovale, CI: confidence interval, P-plateau: plateau pressure, LV: left ventricular, RV: right ventricular.
