Optional up to 2 points of extra credit: Shown is the mean EMQ (Everyday Memory Questionnaire, a test designed to measure memory failure in everyday life) score out to three years comparing SARS-CoV-2 infected vs. uninfected individuals from a study of 111,992 individuals (Prospective Memory Assessment before and after Covid-19, N Engl J Med 2024; 390:863-865). Figure 1. Mean scores on EMQ comparing SARS-CoV-2 infected vs. uninfected individuals; higher scores indicate worse memory problems. 1. What does this graph suggest about infection with SARS-CoV-2? Please explain. Include information and descriptions from the graph to support your explanation. 2. Comparing the trendlines on the left side of the graph to the right side of the graph, what does the trend toward the right side of the graph suggest? Please hypothesize; be sure to include an explanation with supporting information. 3. Comment briefly on the sample size of this study – should this sample size give us confidence in this work? Why or why not? 4. Although the graph does not explain this, propose an explanation as to what the virus might be doing to people that could result in this outcome observed.
