Hi.
I performed mutivariable logistic regression with quartile independent variable. (quartile of BMI)
4th quartile was set as a reference, and Odds ratios for each quartile are as below.
1st : 1.60 (1.39- 1.83)
2nd : 1.33 (1.16-1.52)
3rd : 1.14 (1.01-1.30)
4th : (Reference)
How can I test p for trend of Odds ratio ?
Thanks.
