 ===== ATC data in Lifelines =====
-At [[1A|baseline]], xxx Lifelines participants filled in a questionnaire about their [[medication]] use.
+At [[1A|baseline]], the medication use ([[sections|section]]: [[medical treatment]]) of adult participants were assessed as followed:
+  * By questionnaire (see [[Medication]]), n=xxx (18-64 years old), until July 2012
+  * By medication wrapper brought to [[1A Visit 1]] or [[1A Visit 2]], n=xxx (65+ years old, and 18-64 years old from July 2012 onwards)
+Research assistants coded the results using ATC-coding software. These codes ([[sections|section]]: [[secondary & linked variables]]) are released for research, but please note that not all ATC-coding was verified (i.e. double checked whether the raw data matched the code).
+This is the case for ca. 5,000 participants who did report to use medication at baseline.
+For participants without an atc-code, about 75% was verified.
