Cаse 2 (questiоns 14 аnd 15) Suppоse а researcher is interested in studying whether the use оf ginger helps with pain management in adults with osteoarthritis. The researcher plans on conducting a cross-sectional study in which adults with osteoarthritis treated at Tampa General Hospital are randomly selected for participation. To assess the participants’ exposure status, the researcher plans on asking participants if they consume ginger and to classify participants as either “consumes ginger” or “does not consume ginger”. To assess the participants’ outcome status, the researcher plans on asking the participants to report their current level of pain on a scale of 0 to 100 (0= no pain, 100=worst pain imaginable). Finally, to assess the effect of ginger use on pain, the researcher plans on comparing average pain levels across individuals who consume ginger and individuals who do not consume ginger. The fellow researcher is also worried that there may be reverse causation in the study proposed by the team of researchers in case 2. Explain in the context of case 2 what reverse causality means (max. 5 points).
