    Is my study a case control or a cohort study?




    Hi everyone.
    I'm a student with very little experience or background in biostatistics. My mind is in a bit of a bind and I can't seem to be able to untwist it... Is this study design for a case control study or a cohort study?

    The study design is as follows:
    We enrolled retrospectively all patients who presented with two conditions, having positive HBsAg+ and being immunosuppressed. Variables in study were, for example, age > 65, male sex, having an hematological disease, and some more. Outcome was whether you presented with detectable or undetectable HBV DNA in the serum. We studied the percentage of people among the detectable or undetectable HBV DNA in the serum populations that presented with each of these variables.

    I calculated odds ratio for each of the variables in study, but I don't know if that was the right way to procede in this situation. Would you be able to help me?
    I thank you in advance for your collaboration.

    Case-Control: Select units based on outcome, then determine prevalence of exposures.
