Data entry in Slice revolves around subject data. In order to enter data for a new subject, a project or site editor can create a new subject. Subjects can be created by assigning a new subject code, and then entering the data from the list of available designs.

Designs can be created by project editors at the start of and during a project's life cycle.

When completing a sheet, a sheet completion percentage is calculated. This calculation takes into account the presence of responses in all visible questions. The completion percentage makes it easy to identify sheets that are missing data.

Some designs may have stricter requirements, and have required fields that must be filled in before a sheet can be saved.

Another alternative to making fields required on a design is to set up data quality checks that can help identify sheets that are missing data or have data that is out of range. Data quality checks also have the advantage of being able to compare values across sheets.

Designs can be also set to be publicly available. When a design is publicly available, it is given a public URL, and is called a survey within the system. Designs that have been set as surveys can be filled out by individuals without the need of logging into the site.

Alternatively, a series of designs on an event can be set to be part of a handoff event. A handoff event could occur during a subject visit, and the subject could fill out a series of forms on a tablet before handing the tablet back to the staff member.

Data entered on a sheet is also audited. The audit trail provides information on the time the data was entered, the responses and changes that were made, as well as the individual who made the changes. Audit trails are kept for each sheet.

Sheets can be saved and printed as PDFs if a hard copy backup is needed.

Randomizing subjects can be setup in such a way that it requires a question on a sheet to be filled out before allowing the subject to be randomized.

Project and site members can make comments on existing sheets if they wish to add additional contextual information. If comments frequently attempt to add additional information to the form, it may be a sign that the design requires new questions to be added.

Designs can be assigned to be part of adverse events. Adverse events themselves only have a brief description and date reported. By creating and adding designs to an adverse event, additional information can be consistenly captured across any adverse event that is reported on the project.

Data that is entered on sheets can be exported to a variety of formats. These formats include labeled and unlabeled CSV files along with corresponding data dictionary that Slice build automatically, PDFs, and SAS and R import scripts.

Slice also provides a flexible reporting system that provides preset and configurable reports to generate a series of tables and graphs. These reports can be exported to CSVs or PDFs and reflect the current state of data within the system.
