Decline in age at first diagnosis, 1999 to 2012. The distributions of age at first diagnosis are presented for each year. The thick band inside the box is the median, and the bottom and top of the box are the first quantile (Q1) and the third quantile (Q3). The ends of the whiskers represents data within 1.5 *interquartile range (IQR) from the lower quantile (Q1) or the upper quantile (Q3), where IQR is equal to Q3 minus Q1. The fitted simple linear regression lines are highlighted in different colors (black line: slope = -3.2e-02 (95% confidence interval (CI): -4.3e-02 to -2.2e-02), P value = 3.2e-09, blue line: slope = -2.6e-02 (95% CI: -3.8e-02 to -1.4e-02), P value = 3.2e-05, orange line: slope = -2.9e-02 (95% CI: -5e-02 to -7.8e-03), P value = 7.3e-03). Abbreviation: ASD, autism spectrum disorder.
