From: A sequence variant on 17q21 is associated with age at onset and severity of asthma
Association with rs7216389-T stratified by age at onset of asthma. Cases were stratified by age at onset, and association with rs7216389-T was assessed for each age bin (0–1, 2–3, 4–5, 6–7 years and so on). Cases with onset at 70 years or older were pooled into one single bin (70+). The OR and 95% CI for the mean age of each bin for the combined sample set (Iceland, Australia, United Kingdom, Korea and Germany II) are plotted.
