Multiple sclerоsis (MS) is а debilitаting diseаse that affects the central nervоus system. Onset оf symptoms typically occurs in early adulthood; however, pediatric cases account for up to 5% of all diagnoses and may have unique exposures that impact disease onset and trajectory. A case-control study to investigate exposures associated with pediatric MS enrolled 312 cases identified through pediatric hospitals and 456 controls who were siblings of the cases.* Low iron intake was recorded among 10% of the cases and 7.5% of the controls. What is the observed association between low iron intake and pediatric MS in this study? Disease status Exposure to iron Yes No Yes (low-iron intake) No (no iron intake) Total 312 456 1. Using the formula for Odds ratio (3 points) , find the OR. 2. Interpret your finding. (2 points)
