Showing 11-15 of 20 immunology:
If both total joint counts are populated (tjc_observed) and (tjc_observed_28) and the values are different between them, should we select the largest value as a representation of the number of joints examined?

If the first (tjc_observed) is higher than the second (tjc_observed_28) then, we would advise using the first since that allows for a wider variety of joints to be counted.  The 28 is a specific set of joints that feed into many of the disease activity measures; the broader one allows for any joints (including some[…]

Is anti-CCP and Rheumatoid Factor (RF) available in the OM1 JIA dataset?

We have provided a code set below to help you identify those patients with a lab in the JIA datasets. The anti-CCP positive/negative status is available via the following three LOINC codes: LOINC Code LOINC Name 53028-7 Cyclic citrullinated peptide Ab [Presence] in Serum 63375-0 Cyclic citrullinated peptide IgA+IgG Ab [Presence] in Serum 42898-7 Cyclic[…]

For JIA, can we differentiate pcJIA (polyarticular course) and sJIA (systemic)?

One can approach differentiating between these via diagnostic codes, supplemented with the joint counts. The diagnostic codes that directly refer to the polyarticular status and can be used as a proxy pcJIA are: ICD9: 714.30: Polyarticular juvenile rheumatoid arthritis, chronic or unspecified 714.31: Polyarticular juvenile rheumatoid arthritis, acute ICD10: M08.3 seronegative polyarthritis The above ICD10[…]
