Question: Use the stenosis table below. If you need the full dataset, here is the link: https://convertio.co/download/a5231ac96a222e39b2ae2f8f9fc0ea1746e886/

Please check if my answers below are correct. Also, please don't copy and paste answers.Thanks.

Smokers

Gender Cases Controls Total

Males 37 24 61

Females 14 19 33

Total 51 43 94

Non-smokers

Gender Cases Controls Total

Males 25 20 45

Females 29 47 76

Total 54 67 121

A) What is the odds ratio for developing stenosis for males relative to females (smokers only)?

Odds ratio for developing stenosis for males (smokers): 37/24 = 1.5417

Odds ratio for developing stenosis for females (smokers): 14/19 = 0.7368

Odds ratio of male smokers to female smokers: (Pick one answer below and explain step by step why it's correct.)

A) OR (male smokers) = 37/24 = 1.5417 OR (female smokers) = 14/19 = 0.7368, OR (male smokers/female smokers) = 1.5417/ 0.7368 = 2.092

B) OR (male smokers) = 37/61 = 0.607, OR (female smokers) = 14/33 = 0.424, OR (male smokers/ female smokers) = 0.607/0.424 = 1.43

B) Perform a logistic regression with stenosis as the outcome and sex and smoking status as the explanatory variables.

Please give me the equation. Also, please use statistical software for the question. I would like to see the equation written out for this.

Also, please check which answer is correct below:

My answers is the following:

log (OR) = log (p/ 1-p) = -0.4882 + 0.7199 * sex + 0.1946 * male or

log (y/ 1-y) = -0.4882 + 0.7199 * sex + 0.1946 * male
