Table 2 Adjusted multivariate associations of asthma and ETS exposure with CPC

From: Chronic productive cough in school children: prevalence and associations with asthma and environmental tobacco smoke exposure

Condition Students with CPC N = 173 Students without CPC N = 2224 Odds Ratio [95% CI]
Current Asthma 82 (47%)* 214 (10%) 5.2 [3.6–7.5]
ETS exposure 43 (25%) 180 (8%) 2.9 [1.4–9.4]
Allergic Rhinitis 103 (60%) 549 (25%) 2.6 [1.9–3.8]
Female gender 108 (62%) 1108 (50%) 1.5 [1.0–2.1]
  1. *The numbers in parentheses are the percent of students in each group who have the condition; i.e., 82/173 (47%) of children with CPC had current asthma.
