AOM, acute otitis media; C-AOM, clinically-confirmed AOM; CI, confidence interval; post-booster, at the time of or after booster vaccination; intent-to-treat analysis, follow-up starting at the time of first vaccination. Vaccine efficacy was calculated as (1 – hazard ratio) x 100 using a Cox (first episodes) or generalized Cox (all episodes) regression model.

^aAll C-AOM episodes, including multiple episodes in the same child.

^bFollow-up time for first episodes calculated as sum of follow-up periods of each child, censored at the first occurrence of a respective endpoint event.

^cFollow-up time for all episodes calculated as sum of follow-up periods of each child, from dose 1 up to end of follow-up.

^dPost-hoc analysis

^eC-AOM episodes with complete reporting of information for all 5 symptoms (~80% of all reported C-AOM cases) on the clinical/otologic scale developed by Dagan et al.³³

^fC-AOM episodes with information for at least 1 symptom on the clinical/otologic scale developed by Dagan et al.³³; unrecorded symptoms were assumed not to be present in the patient.
