For most epidemiological questions, I always refer as a first source of reference Rothman and Greenland (and Lash)'s Modern Epidemiology (1998 or 2008). For a quick answer though, I'd use unconditional logistic regression for frequency matched data.

Hi All,
I am putting together a protocol on lung Cancer and occupational categories a case control study.
I will match by age and gender. I am sure whether to use frequency matched cases control, unconditional logistic analysis or conditional logistics analysis
Can anyone throw more light on the above terminologies and the best approach for this analysis?

Regards,
