What is the correct interpretation of the effect of biomarker level on risk of death in the attached logistic regression model.

Coefficients and their standard errors for a logistic regression model of biomarker levels against risk of death, corrected for age

Coefficient. SE. df P

Constant. -7.729. 0.191 1 0.01

Biomarker - 1.16. 0.071 1 0.002

Age- 0.050. 0.0001 1 0.0001

• A.A one unit increase in the biomarker is associated with a 16% increase in odds of death
• B.The effect of the biomarker is not significant at the .05 level
• C.A biomarker level that increases from 2 to 3 increases odds of death 3.19 times
• D.A 50 year old person with a biomarker level of 3 has a risk of death of less than 5%
