Multinomial univariate and multivariate regressions with clinical diagnosis as the outcome (URTI was used as base category)

	Univariate analysis	Multivariate analysis
Covariate	Beta-coefficient (95% CI), p-value	Beta-coefficient (95% CI), p-value
Age	AOM vs URTI −0.087 (−0.13 - (−0.044)), < 0.001 Sepsis vs URTI 0.038 (0.016–0.060), 0.001	AOM vs URTI - 0.091 (− 0.14 – (− 0.047), < 0.001 Sepsis vs URTI 0.041 (0.018–0.063), < 0.001
igaB vs all	Sepsis vs URTI − 1.69 (−3.00 – (− 0.38)), 0.012	Sepsis vs URTI −1.86 (−3.22- (− 0.49)), 0.008
igaA2 vs all	no significant category

The analysis was performed for isolates with igaB genotype vs all other isolates as well as those with igaA2 genotype vs all other isolates. Only statistically significant associations are presented
