TABLE 4.

Frequency of symptoms among children with red/yellow PFM readings vs. green PFM reading (each child only counted 1 time).

	Red/yellow (n = 131)	Green (n = 159)	p value
Symptoms
Cough	74 (56%)	83 (52%)	0.47
Wheeze	50 (38%)	49 (31%)	0.19
Tightness in chest	55 (34%)	39 (25%)	0.09
Trouble breathing	41 (31%)	34 (21%)	0.06
Number of symptoms
None	39 (30%)	65 (41%)
1–2	55 (42%)	60 (38%)	0.12
3–4	37 (28%)	34 (21%)

The children who always exhibited green peak flow meter readings trended toward fewer symptoms on their “worst” days; however, none of these differences were statistically significant.
