Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Rheumatoid arthritis (RA) disease activity is measured using the DAS28 score, HAQ score at baseline and one year 2. Periodontal parameters (such as probing pocket depth, clinical attachment loss) are measured using the methods of measurement of periodontal disease/parameters at baseline and months three, six, nine, and twelve | — |
Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures as of 23/09/2025: 1. The microbial profile is assessed using sequencing technology throughout the study (the specific time points depend on the availability of the resources as well as the instruments at core facility) 2. Antibody levels (such as ACPA/RF, periodontal pathogens etc) are measured using multiplex immunoassay, nephelometry and/or ELISA technique at baseline and one year 3. Levels of inflammatory mediators are measured using Luminex immunoassay at baseline and one year 4. Metabolome profile measured using liquid chromatography–mass spectrometry (LC/MS) at baseline and one year Previous secondary outcome measures: 1.
