2. FIG 1
Odds ratios for the association between allergic rhinitis and asthma among respondents to the European Community Respiratory Health Survey postal questionnaire and combined odds ratio (dashed line) derived from individual odds ratios estimated at each center, calculated with the standard method for meta-analysis. The horizontal lines and the diamond indicate the width of the 95% CI of the odds ratio for each center and of the combined odds ratio, respectively.

4. FIG 3
Proportion of subjects with asthma for subjects without rhinitis (white bar n = 7449) and subjects with symptoms of rhinitis only when exposed to pollen (dotted bar n = 609), subjects with rhinitis when exposed to animals or dust (hatched bar n = 428), and subjects with either symptoms of rhinitis when exposed to pollen and to animals (black bar n = 1308).
