Being sensitized to both shrimp and mites was independently associated
with having angioedema, wheeze, and chronic airflow limitation, after
adjusting for age, sex, and birch and cat sensitization. Being
sensitized to shrimp or mite alone was associated with having urticaria
(Table 2). There was also an independent association between lower
FEV1 (% of predicted) and sensitization to both shrimp
and mites: -3.5 (-6.5, -0.5) % of predicted units.
