What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To investigate whether the method used to determine body composition affects the diagnosis of malnutrition when applying the GLIM criteria.

    This will be conducted via BIA- and DXA-scans and with the use of GLIM criteria

    Measured: Time of inclusion and/or 14 days after preliminary inclusion.

    mGFRDBS will be performed and the biomarkers will be analyzed afterwards for making this analysis

    Measured: From enrollment to 6-8 hours later same day (when mGFRDBS is completed)

  3. To evaluate the performance of eGFR based on creatinine, cystatin C, B2M, and BTP relative to mGFRDBS in patients aged ≥90 år (patients from groups 1 and 3)

    mGFRDBS will be performed and the biomarkers will be analyzed afterwards for making this analysis

    Measured: From enrollment to 6-8 hours later same day (when mGFRDBS is completed)

  4. To evaluate the performance of eGFR based on creatinine, cystatin C, B2M, and BTP relative to mGFRDBS in patients with BMI ≥35 kg/m2 (patients from groups 1 and 4)

    mGFRDBS will be performed and the biomarkers will be analyzed afterwards for making this analysis

    Measured: From enrollment to 6-8 hours later same day (when mGFRDBS is completed)

  5. To determine changes in mGFRDBS during and after treatment with ≥37.5 mg daily prednisolone (patients from group 5)

    mGFRDBS will be performed twice

    Measured: From enrollment to approximately 10-35 days after prednisolone treatment

What does the primary outcome measure?

To investigate whether the method used to determine body composition affects the diagnosis of malnutrition when applying the GLIM criteria. (time frame: Time of inclusion and/or 14 days after preliminary inclusion.). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
