  2. Note: HFaST values are as follows: 0 = Did not experience in the past 24 h, 1 = Much better than usual, 2 = Somewhat better than usual, 3 = Slightly better than usual, 4 = About the same as usual, 5 = Slightly worse than usual, 6 = Somewhat worse than usual, 7 = Much worse than usual
  3. Table excludes patients who reported HFaST = “Did not experience” for PGISS Change From Day 4 to Day 5 and HFaST Day 5
