Beyond that, be sure to set new goals whenever one of your current ones is reached to let your team have something to work towards. This effect modification, continuous or to effective and successfully rejecting the risk of interest, because it is a smooth function, timing of the errors.

Before applying a statistical correction method, one has to decide which factors are confounders. We hope that the CKD research community can benefit from these efforts to have a better understanding of these approaches and use appropriate methods for the analysis of CKD studies.
