A Case-Control Study is not characterized by

We cannot measure the incidence and can only estimate the relative riskAdvantages of Case-Control StudiesThey are efficient for rare diseases or diseases with a long latency period between exposure and disease manifestation.They are less costly and less time-consuming; they are advantageous when exposure data is expensive or hard to obtain.They are advantageous when studying dynamic populations in which follow-up is difficult.Disadvantages of Case-Control StudiesThey are subject to selection bias.They are inefficient for rare exposures.Information on exposure is subject to observation bias.They generally do not allow calculation of incidence (absolute risk).Park 23e pg: 74
