- | ==== 3. Extract the Data: ==== | ||
- | |||
- | Once you have finished establishing the Study Arms, you are ready to extract the data from the underlying study. The first step in doing so, for each Data Element, is establishing the Measurement Timepoint for each Data Element. | ||
- | |||
- | === 3a. Select Measurement Timepoints === | ||
- | |||
- | Each Data Element has one Timepoint presented by default; select whether this timepoint will be: | ||
- | |||
- | * **Baseline: **Usually reported at the start of a study. One Baseline timepoint per Data Element will be displayed on Synthesis. | ||
- | * **Outcome: **Reported at a designated follow-up period. One Outcome timepoint per Data Element will be displayed on Synthesis. | ||
- | * **Other: **Any additional timepoint reported that is of interest. Any number of Other timepoints may be created and saved in AutoLit, but // | ||

- | === 3b. Enter Time and Units for each Measurement Timepoint === | ||
- | |||
- | For each Timepoint, enter the follow-up period with the appropriate unit of time (Days, Weeks, etc.). For Baseline Timepoints, this will typically be 0 days. | ||

- | === 3c. Extract the Data for each Measurement Timepoint === | ||
- | |||
- | Read through the study and extract the relevant data scoped to each specific Timepoint. **//If the total population for that Data Element differs from the total population you reported for the Study Arm as a whole, ensure that you edit this information in the " | ||

- | === 3d. How to use Tags to inform Extraction === | ||
- | |||
- | If you hover over the tag symbol on each data point, you will notice that the tags applied will appear. This allows for a quick and efficient way to confirm the work of the taggers, as well as the tags giving information to you as the extractor. | ||
