Physical Activity and COVlD-19 Outcomes The questions below are based on the following article: Cho DH, et al. Physical activity and the risk of COVlD-l’? infection and mortality: a nationwide population-based case-control study f’-.>. J Clin Med, 2021, doi:10.3390fiicm10071539 f—p 1. Discuss the possibility of selection bias in this study, using the example of the physical activity vs. COVID-19 infection. Be sure to address all of the following: a) What features of this study would give rise to selection bias, and bi Is this selection bias likely to result in an over- or under-estimation of the true odds ratio? (Use the lectures as your guide). c) What measures have the authors already undertaken to minimize the risk of selection bias? cl) What other measures would you undertake to guard against selection bias if you were in charge of this study? 2. Similarly, discuss the possibility of information bias in this study. also using the example of physical activity vs. COVlD-19 infection. Address the same points with respect to information bias: a) What features of this study would give rise to information bias, and b) Is this information bias likely to result in an over- or under-estimation of the true odds ratio? (Again, use the lectures as your guide). c) What measures have the authors already undertaken to minimize the risk of information bias? cl) What other measures would you undertake to guard against information bias if you were in charge of this study?
