^*For 43 scenarios, no post-test information sources were recorded, and these cases are excluded from this table, which examines changes in the direction of pre- and post-test responses. These scenario responses were excluded because they did not meet the definition of a correct answer as specified in the Methods section, namely, the provision of an answer and an accompanying information source found using the online information system to support the answer.
