After logging in, the main menu bar contains a grey ‘search’ box, which is retained throughout Skylark. This will perform a simple keyword search at any time during your Skylark session. Keyword searches will return matches from variable names or labels, and are not case sensitive. | After logging in, the main menu bar contains a grey ‘search’ box, which is retained throughout Skylark.

+ | Due to restrictions placed on us by NHS Digital, we are unable to share certain restricted data outside of the Unit. These variables will not appear in any search results. Data restricted in this way includes: | ||
+ | |||
+ | * Mortality data | ||
+ | * Cancer registrations | ||
+ | * Hospital episodes (HES) | ||
+ | |||
+ | If you think your project may require access to these kinds of data, __or__ other sensitive variables unavailable via Skylark due to a raised level of risk of reidentification to NSHD study members, please [[mrclha.swiftinfo@ucl.ac.uk|contact us]]. It may be possible for you to access these data from inside the Unit. | ||
