Dear Developer,

I would like to inquire about the preparation of the sdm_table file when performing covariate regression in mean analysis. Taking age as an example, specifically, should we regress the ages of cases and controls separately, or only regress the age of the case group? or if we merge the ages of the case and control groups into a single column after computing a weighted average, and then perform regression?Looking forward to your response.
      Thank you！

      Best,

      Ying Zhai
