Note.—Unless otherwise indicated, data are mean plus or minus standard deviation. Reported P values are adjusted for three independent t tests. P < .05 indicates a significant difference. Pre = before TIPS placement, Post 1 = 2 weeks after TIPS placement, Post 2 = 12 weeks after TIPS placement.
*
Data are mean differences, and data in parentheses are 95% CIs.
