Sensitivity and specificity of elevated serum CRP for predicting Streptococcus pneumoniae and/or Haemophilus influenzae ABRS.

	Sensitivity	95% CI	Specificity	95% CI
Streptococcus pneumoniae	0.57	0.25–0.84	0.63	0.50–0.74
Haemophilus influenzae	0.80	0.49–0.94	0.69	0.55–0.79
Streptococcus pneumoniae or Haemophilus influenzae	0.71	0.47–0.87	0.72	0.58–0.83

CRP, C reactive protein; ABRS, acute bacterial rhinosinusitis; CI, confidence interval.
