TABLE 4.

Frequency of colony counts on throat swabs taken at enrolment and follow-up for patients with and without treatment failure

	Patients with GABHS treatment failure (n=29)		Patients without GABHS treatment failure (n=65)*
Colon count	Pretreatment (%)	Post-treatment (%)	Pretreatment (%)
Rare	1 (3.4)	0	3 (4.6)
1+	0	1 (3.4)	3 (4.6)
2+	4 (13.8)	6 (20.7)	5 (7.7)
3+	4 (13.8)	4 (13.8)	8 (12.3)
4+	20 (69.0)	18 (62.1)	46 (70.8)

^*χ² for trend, P=0.46 for both pretreatment groups. 1+ if less than 10, less than five, zero and zero colonies; 2+ if greater than 10, greater than five, less than five and zero colonies; 3+ if greater than 10, greater than 10, greater than five and less than five colonies; 4+ if greater than 10, greater than 10, greater than five and greater than five colonies.
