For an active reviewer, what does the button labeled 'Start Review' initiate?

The button labeled 'Start Review' is intended to begin the process of document analysis within a review platform. When an active reviewer clicks this button, it signifies the commencement of a thorough evaluation of the documents at hand. This involves examining the content of the documents, assessing their relevance, and determining how they fit into the context of the review project.

While coding documents may be part of the overall review process, the term 'document analysis' more accurately encompasses the broader scope of activities that an active reviewer engages in after clicking 'Start Review.' This involves not only coding but also interpreting information, identifying key themes, and making decisions based on the content.

The other options do not accurately represent the function of the 'Start Review' button. Accessing document metadata or opening user settings would not initiate the review process itself, and thus, do not align with the primary action that an active reviewer is expected to take when starting their review activities.
