Significance of platelet count in children admitted with bronchiolitis

Table 3 Degree of thrombocytosis and outcomes in 305 children with bronchiolitis

	Thrombocytosis, n (%)				P value
	None (n = 217)	Mild (n = 78)	Moderate (n = 9)	Severe (n = 1)
Mean (SD) duration of hospitalization in days	4.0 (5.5)	4.4 (4)	4.5 (3)	5.0 (0)	0.91
Admission to ICU	25 (11)	25 (30)	3 (33)	0 (0)	0.22

¹ANOVA with Bonferroni correction for multiple comparisons;

²Fisher exact test. n: Number of infants; Thrombocytosis: None if platelet level < 500 × 10⁹/L; mild if 500 to 700 × 10⁹/L; moderate if 700 to ≤ 900 × 10⁹/L and severe if > 900 × 10⁹/L. ICU: Intensive care unit.
