From: Agreement between self-reported and registered age at asthma diagnosis in Finland
Bland-Altman plots of agreement between self-reported and registered age at diagnosis from Helsinki (A–D) and Western Finland (E–H) study populations. (A,E) population with less than 10 years elapsed from self-reported asthma diagnosis, (B,F) population with 10 or more years elapsed from self-reported asthma diagnosis, (C, G) population without allergic rhinitis, (D, H) population with allergic rhinitis. Solid line (━) represents median, and the dashed lines (- - -) represent limits of agreement (90% of the measured values). Shaded area represents 95% confidence intervals. In (A, E, G, H) all 95% CI:s could not be calculated
