    Analysis of covariance (ANCOVA) and risk estimates on continuous variable

    Dear All
    I have done Analysis of covariance (ANCOVA) on a RCT data. The outcomes are continuous (quality of life and coherence). I used the ANCOVA to estimate the between-group differences adjusted for pre-test values; age, gender, and education. I presented then f values and p values. However, a reviwer wrote me “It would be useful to provide risk estimates in your results section, to assist in the reader being able to interpret the analysis. The use of an f value is unusual and not easy for a reader to understand”. It is very odd! Because we don’t have a risk estimate in the continuous variable. Do you have any ideas? Thanks in advance

    I can help you better if you tell me what the "treatment(s)" is/are. Your outcome is continuous and you offer three covariates, but no treatment.

    It appears your reviewer wants to know "to what extent..." instead of merely "there is an interaction and we are confident it did not just happen by chance."
