#TFQOD #MBA #CAT2014 Check out our Last Years CAT Question Of the Day. Answer the question based on the passage given below. Smoking just a few cigarettes a day more than doubles a womans risk of developing rheumatoid arthritis. A Swedish study found that women who smoke only a small number of cigarettes a day significantly increase their risk of developing the condition. This large study followed more than 30,000 women from two Swedish counties over a seven-year period to look at whether smoking increased their risk of developing rheumatoid arthritis. Smoking is already recognized as a possible risk factor for developing the condition. But this study showed that the risk increased even at relatively low levels of smoking. It found that even smoking as many as between one and seven cigarettes per day more than doubled a womans chance (2.31 times) of developing rheumatoid arthritis compared with a woman who had never smoked. Which of the following casts the most serious doubt on the conclusion of the study? OPTIONS 1) It is not clear how many women dropped out of the study which could have biased the results. 2) It is unclear whether similar risk patterns would be seen in men (the condition is more common in women) or a more ethnically diverse group. 3) Previous studies have shown that cigarette smoking was directly associated with a higher risk of developing rheumatoid arthritis. 4) It could be that different ethnicities may have different risk profiles for developing rheumatoid arthritis.
