Factors Associated With Streptococcus pyogenes Colonization in the Live Attenuated Influenza Vaccine Group (n = 212)

	OR	95% CI	P Value
Day 7 vs day 0	1.30	.57–2.97	.540
Day 21 vs day 0	3.18	1.49–6.81	.003
Positive respiratory virus at day 0	1.54	.72–3.29	.266
Age in months	0.97	.93–1.01	.162
Sex male vs female	0.97	.47–2.04	.945

P values for factors associated with Streptococcus pyogenes colonization are derived from a generalized logistic mixed effects model, taking into account changes within individuals over time. Bold signifies a P value of <0.05 considered statistically significant.

Abbreviations: CI, confidence interval; OR, odds ratio.
