stats- data analysis

The coefficients in a logistic regression model can be interpreted as odds ratios if you exponentiate them. In other words, the odds ratio for the treatment program are:

$e^{-2.73309} = 0.06501807$

If you had two people who had the same level of anxiety, but one of them completed the program and one of them didn't, the odds of a second heart attack for the person who completed the program would be equal to the odds of the person who didn't complete the program multiplied by 0.06501807, which is effectively reducing the odds by 93.5%. So the fifth answer is the correct answer.
