6. A study was conducted to examine risk factors for spontaneous pneumothorax (collapsed lung), including use of car air fresheners. 430 emergency room cases were identified from Florida hospitals in 2005, and 1204 controls were sampled from the patients admitted to the emergency room for broken bones or lacerations. It was found that 110 of the cases and 214 of the controls used a car air freshener regularly. The remaining cases and controls did not use air fresheners in their car. a. Assemble the 2x2 table for this study using the information given. b. Calculate the odds of being a case among the unexposed c. Calculate the odds ratio for disease given exposure to regular car air freshener use compared to no air freshener use. d. What does the odds ratio indicate?
