During the ongoing Data extraction process You can modify form in one of the following methods: 

• By spreading existing vocabulary and adding additional terms

• By adding  or updating field instructions

• By changing or adding AI models, input validation and key fields 

• By editing Input Validation, Required Field and Key Field Selection

  
  

Adding additional terms to the existing vocabulary 

To add new terms to your uploaded vocabulary, locate the specific vocabulary and add new terms in the "Additional Terms" area below the uploaded vocabulary. Once you have made your changes, click 'Save Form'.

 If you have uploaded a vocabulary with only part of its concepts, you can update this vocabulary with the rest of concepts from this vocabulary.

Example: 

During the data extraction you noticed that only vocabularies for experimental and observational studies were selected. If other study types have been added to the vocabulary previously, you can add more study types to the vocabulary in the data extraction.

Note: in the case of updating vocabularies, the changes will be visible immediately after saving them, both for distributed and non-distributed PDFs 

Adding or updating field instruction 

To add or update a field description, locate the specific field and write a new description or modify existing one. Once you have made your changes, click 'Save Form'.

Note: If you update or add a field instruction, the changes will be visible immediately after saving, for both distributed and non-distributed PDFs.

Note: If you update or add a field instruction, the changes will be visible immediately after saving, for both distributed and non-distributed PDFs.

Model Suggestion Update

If you want to change Model Suggestions, locate the specific field and in the ‘Advanced settings’ section, exchange the existing suggestion to the new one. 

Once you have made your changes, click 'Save Form'.

Note: in the case of changing model suggestions, the changes will be available only for new distributions

Editing Input Validation, Required Field and Key Field Selection

You can make additional changes related to the targeted fields. 

• Required field - this option informs the Researcher that a particular field should be extracted, while they try to send the extraction without filling in these fields.

• Key field - enables you to decide if this field should be used as an object name 

• Input validation - This function allows you to verify if the extracted value is consistent with your assumptions (to see more information, check “Input validation” section)

Note: In the case of editing required field, input validation and  key field, will be available only for new distributions

Data Extraction form modification - load new template after distribution 

If major changes need to be made to the extraction form, a new template can be uploaded.

To upload new template, in the ‘‘Data Extraction form’ tab choose ‘Load template’ button. You will be redirected to the list of available templates to be uploaded. 

Note that complete change of form will cause loss of data in the Extraction Summary for all previously extracted studies - The Extraction Summary table is reset to only contain data based on the new template
