  • Group 1—immediate antibiotics alone (control); group 2—immediate antibiotics and immediate cranberry; group 3—immediate cranberry and delayed antibiotics.

  • *Group 2 and group 3 were compared with group 1 (controls).

  • †Model adjusted for site.

  • ‡The mean symptom burden for each participant was calculated by summing the total ratings for all symptoms between day 2 and day 4 (inclusive) and dividing this by the number of symptom ratings made by the participant between day 2 and day 4 (inclusive).

  • N/A, not applicable.
