Summary

This completed study screened over 8,400 Brazilian adults with known risk factors for chronic kidney disease (CKD) using a portable creatinine test. Participants were randomly selected from five regions. Those with abnormal results were referred for lab confirmation and follow-up care. The goal was to estimate how many people have undiagnosed CKD in Brazil.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help identify how common undiagnosed chronic kidney disease is in Brazil, guiding future screening programs.
What could go wrong
This is an observational study, not a treatment trial. It only estimates prevalence and does not test any intervention or cure.
