The odd ratio (OR) between the cases (welding fumes) and the outcome (COPD) was reported as 3.0 (assuming the result is statistically significant). Which of the following statements accurately interpret the results? Group of answer choices Cases of COPD were 3 times as likely as the non COPD subjects to be exposed to welding fumes. Subjects who were exposed to welding fumes have a 3 times higher risk of developing COPD than for those who were not exposed to welding fumes. Welding fumes workers have 30% higher risk of developing COPD than workers who were not welders. All of the above.

Step 1
0 means. An OR of 3.0 indicates that the odds of the outcome (COPD) are 3 times higher in the exposed group (welding fumes) compared to the non-exposed group. Show more…

2. The association between job-related exposure to welding fumes and chronic obstructive pulmonary disease (COPD) was explored in a case-control study. The following data were reported for 399 COPD patients: 42 currently employed as welders; the remainder had no occupational exposure. Among the 700 controls, 47 were employed as welders. Set up a 2 by 2 table and calculate the OR.

A sample of Cleveland residents was taken to examine the relationship between smoking and COPD (chronic obstructive pulmonary disease). The study found that the prevalence ratio of COPD in non-smokers who live with smokers compared to in non-smokers who do not live with smokers was 2.0. The 95% confidence interval for this prevalence ratio was 1.8 to 2.2. 7. What is the exposure variable (i.e., independent variable)? COPD Smoking Cleveland 8. What is the prevalence ratio of COPD in non-smokers who live with smokers compared to non-smokers who do not live with smokers shown above called (since it comes from a sample of the population in Cleveland)? Parameter Median Interval estimate Point estimate 9. What would the same measure (prevalence ratio of COPD in non-smokers who live with smokers compared to non-smokers who do not live with smokers) be called if it was from the entire population in Cleveland? Parameter Median Interval estimate Point estimate

A cross-sectional study on the association between COVID-19 symptoms and the risk factor of smoking reported an odds ratio of 1.5 with a 95% confidence interval of 1.42 to 1.58. What is the correct interpretation of these results? Those with COVID-19 symptoms were 50% more likely to smoke compared to those without COVID-19 symptoms, and this difference was statistically significant.
