What is a possible outcome of adding a large number of new documents to the project during review?

Adding a large number of new documents to the project during review can lead to a decline in relevance rate. The inclusion of these additional documents often means that reviewers must examine a greater volume of information, which can dilute their focus and potentially result in lower consistency in relevance assessments. It assumes that the new documents may not align closely with the relevance criteria established for the existing documents.

When new documents are introduced, it can also shift the overall context or subject matter of the review, making it more challenging to maintain a high relevance rate if the newly added documents are varied in quality or relevance to the project goals.

Increased coding time is also a likely outcome since reviewers would need to allocate extra time to assess and code the new documents, leading to further examination and categorization that may not have been required initially, thereby affecting the overall efficiency and effectiveness of the review process.
