Hi, Statalisters:
I am not so much good in posting on the forum, please excuse me for not adhering the rules.
My setup (Windows 10, Stata 16.1 MP)
My objectives:
  1. To see the moderating effect of wealth status on the relationship between
Intimate Partner Violence (IPV) and antenatal care (ANC) service
  1. to see the average marginal effects of the models
  2. Stratified by wealth status (Low wealth vs. High wealth) in the associations between IPV and ANC
Note that my all independent, dependent and moderator variables are categorical.

The Stata outputs are attached with this post.
My question: I found non-significance in the interaction model and in the marginal model but found the significance in the stratified model (shown in the above regression output).
So, I don't understand why the results in the interaction model and in the marginal model don't show the significance that found significance in the stratified model.

So, what you would advise about doing the stratified analyses, or just use the marginal effect tables or both? Any possible explanation you have, please.
Thank you so much in advance for your quick response.
