Correlation coefficients of age, intubation time and ICU admission days with baseline SPAP and the fall in this value immediately after operation and in the follow-up

	Preop SPAP	Differences in Preop and early postop SPAP	Differences in early and late postop SPAP
Age	0.057	−0.077	0.146
Intubation time	0.039	0.085	0.442*
ICU admission	0.065	0.146	0.357

SPAP: systolic pulmonary arterial pressure; ICU: intensive care unit.
