Table 3 Subgroup analysis of the congruence between prescription of asthma medication and doctor-diagnosed asthma.

From: Prescription of respiratory medication without an asthma diagnosis in children: a population based study

  N Asthma medication use, % Doctor-diagnosed asthma, % PPV* Sensitivity
Total population 74,580 7.5 4.1 0.49 0.89
Male 38,267 8.3 4.6 0.50 0.89
Female 36,312 6.7 3.5 0.47 0.90
<6 yrs 21,720 10.8 5.7 0.46 0.88
≥6 yrs 52,860 6.2 3.5 0.51 0.90
SABA only   2.5 4.1 0.38 ^
ICS only   1.6 4.1 0.42  
SABA + ICS   3.0 4.1 0.64  
1 prescription   4.0 4.1 0.38 ^
2 prescriptions   1.6 4.1 0.54  
≥3 prescriptions   2.0 4.1 0.66  
  1. * All Pearson's Chi-Square p-values < .0001
  2. ^ The sensitivities for subgroups of asthma medication users are not shown, since they are highly dependent on the percentual contribution of the subgroups to the total group of asthma medication users and are therefore not very informative and, by definition, low.
