Logistic regression analysis for predicting neutropenia <1.0 × 10⁹/L in infants with RSV infection.

	Odds Ratio (95%CI)	p Value
Any of the 3 bacteria † identified in cultures of nasopharyngeal aspirate	0.11 (0.03–0.35)	<0.0001 *
Age at onset of RSV infection, per 1-month increment	0.81 (0.65–0.97)	0.020 *
GRSS on admission, per 1-point increment	0.92 (0.67–1.24)	0.59
C-reactive protein, per 1-mg/L increment	1.02 (0.99–1.05)	0.10
Female infant	1.49 (0.61–3.70)	0.38

CI: confidence interval; GRSS: global respiratory severity score; RSV: respiratory syncytial virus. * p < 0.05; ^† Moraxella catarrhalis, Streptococcus pneumoniae, or Haemophilus influenzae.
