'''The research question you are planning to answer with the variables above:'''

We will test whether the time to complete the touchscreen questionnaire can be used as an indicator of reading ability. If so, we will perform a genetic association analysis. Visual acuity variables are included as possible confounders. Field 393, which is sensitive, is absolutely required for this purpose. Completion time of the touchscreen questionnaire is likely to be dependent on the version of the touchscreen software used by a participant. We will need to segment our analysis using this variable.
