mean percentage change in the RII for each one-unit increase in the year variable
^aDiseases/adverse events included: From 0 to 14 years old: asthma, bronchitis, injuries and poisoning. From 0 to 2 years old: congenital anomalies and adverse birth outcomes (short gestation, low birth weight and fetal growth retardation).
