Text: Propranolol reduced PPG (mean + / - s, mmHg) significantly (14. 8 + / - 3. 7 versus 12. 1 + / - 3. 7 ; -21 % + / - 10 % ; P < 0. 001), while nitrates alone (14. 3 + / - 3. 4 versus 13. 7 + / - 3. 4 ; -11 % + / - 3 % ; P = 0. 06) or nitrates plus propranolol (12. 9 + / - 4 versus 12. 4 + / - 4 ; -7 % + / - 8 % ; P = 0. 2) induced only minor additive effects on portal pressure.
