Implementation of the standalone eFI-CGA's main features.

Main Feature	Purpose	Implementation
Preview	Opens a one-page screenshot of the entire form for reviewing trends in the data and alerting to missing fields	When “Preview” is selected, the application saves a screen shot of the sections of the form and joins them together to create a single image.
User manual	Opens the user manual for item-by-item instructions on completing the eCGA items and usage of the Standalone eFI-CGA application	When “User Manual” is selected, the application opens the User Manual pdf file if it is pre-stored in the same folder of the software.
Calculate eFI-CGA	Automates an eFI-CGA score to 4 decimal places with 100% accuracy	When “Calculate eFI-CGA” is selected, the application maps inputs to coded values, uses the coded values in the FI-CGA algorithm, and outputs the eFI score.
Save records	Saves the inputs into files of various types	Once every 3 min, when “Save Records” is selected, and at the closure of the software interface, the application saves all inputs to various files.
Reset	Resets the application and returns the user to Page 2	When “Reset” button is pressed, the application clears all fields and opens Page 2.
Input validation	Prevents the user from entering incorrect information	The application ensures correct input format (e.g., string, integer) and the logical relationships between variables.
Missing data handling	Ensures that the user does not miss required information necessary for valid eFI-CGA calculation	When “Calculate eFI-CGA” is selected, the application checks every required field and prompts error messages if there are any missing fields.
