st: compare small sample size with very large sample size

Cost Comparison:
based on patient admission and treatment duration for non-alcohol related diagnosis.
Groups
Alcoholic group vs. Non alcoholic group
Sample 43 patients Vs. sample size 21,028 patients
107observations Vs. 24,204 observations
The data is obtained from a patient registry.
Is it possible to compare such small sample size with very large group??????????????????? if yes what is stata command should i apply????
..If that is no, which i think it is! How about selecting 50 patients from the non alcoholic group???? will that lead to a bias??
Could anyone please comment?????
Kind Regards,
Moumin
