To assess the factors associated with early treatment patterns, questions evaluated included pain severity and associated symptoms, activities at onset of migraine, timing and selection of medication, physician-level variables, and co-morbid headache diagnoses.

To gain more insight into drinking patterns, questions were also asked about 'How many SDs did you on average consume per occasion?' and 'What is the highest number of SDs you have ever consumed in the previous 12 months?'.
Which brings us to the pattern question posed earlier: What comes next after 28, 23, 18 and 14? Actually, it's a math teacher's idea of a joke.
The meal pattern question was "How many of these meals (breakfast, lunch, dinner and snacks) have you eaten during the last week?".
However, a recent study using cells grown on micro-patterns questions this notion since isolated cells without cell-cell contacts cannot polarize in response to adhesion [27].
The pilot study allowed the OPTIC team to identify and rectify "glitches" in the T3 such as missing "other", "not applicable" and/or "not recorded" options, and incorrect skip pattern questions.
Descriptive statistics were used to identify the individual questions and patterns of questions that were most commonly characterised as not applicable in the three questionnaires.
