Proportion of Stroke/TIA Population with Stroke Diagnosis. The percent of stroke or TIA diagnoses with a primary stroke diagnosis by year and by age group (all ages, 18–44 years old, 45–64 years old, and 65+ years old). Error bars represent 95% confidence intervals. There is no evidence of a linear temporal trend in the all ages group (adjusted OR 1.001, 95% CI 0.982–1.021, p = 0.896) or trends in the young (adjusted OR 1.018, 95% CI 0.933–1.109, p = 0.692) or older adult populations (adjusted OR 1.005, 95% CI 0.982–1.029, p = 0.648). For the 18–44 years old group, the proportion of stroke/TIAs with stroke diagnosis was 1 in 1995, so this year was not included in the logistic model, and thus, lacks error bars
