Confidence Intervals of LTA transitions with covariates

ABunting — Fri, 07 Feb 2020 21:24:15 GMT

Greetings and thank you for the advice.

I have completed a LTA with 3 time periods and covariates. Covariate1 predicting T1 status is not significant-it is a control for the intervention versus treatment group. For the transitions I am interested in 2 variables predict the LTA transitions. My output provides me with the Odds Ratios for these transitions- but I'm not seeing where it would be noted that these transitions are significant or if a 95% CI can be obtained for the odds ratios? In many publications I do not see significance indicated but have seen one publication with CIs given. Thank you!
