st: crude odds ratio (crude?)

I have to perform logistic regressions.
For references, I use:
Stata (manual and software)
Applied Logistic Regression (Hosmer & Lemeshow)

I'm reading some articles where logistic regressions are used:  crude
odds
ratio are reported.  Here, crude seems to be a technical word.  Crude
odds
ratio is not in the index of Applied Logistic Regression.  From Stata, a
net
search with crude as a key word (crude, crude odds ratio) produced not
matches.

Suppose that y , x1, x2, x3, x4, x5 are variables coded 0-1.
Here, y is the dependent variable,
and x1, ..., x5 are the independent variables.
I have two questions.

When crude odds ratio of x1 are reported,
does it come from the syntax
logistic y x1 ?

When odds ratio of x1 adjusted for x2, x3 and x4, are reported
does it come from the syntax
logistic y x1 x2 x3 x4 ?

Thank you.
