Racial and Ethnic Differences in a Biochemical Marker of Rheumatoid Arthritis Disease Activity.
Article in ACR open rheumatology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05530694 (Implementation of Shared Decision Making in Rheumatoid Arthritis), which is not on this map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
objectiveRacial and ethnic disparities in rheumatoid arthritis (RA) disease activity measures have been documented. We compared racial and ethnic differences in disease activity using multiple composite measures, including an objective measure, the multi-biochemical disease activity (MBDA) score.
methodsData are derived from the University of California, San Francisco RA Cohort, a longitudinal observational cohort. Participants with at least one MBDA measure and self-reported race and ethnicity were included. Multivariable linear regression evaluated the association between race and ethnicity groups and mean MBDA score, adjusting for potential confounders, including symptom duration and medication use. Sensitivity analyses substituted the Clinical Disease Activity Index (CDAI) and the Disease Activity Score-28 joints with erythrocyte sedimentation rate (DAS28-ESR) for the MBDA in multivariable models.
resultsWe included 267 participants (86% female, mean age 52.7 ± 13.3 years). The majority were Latinx (n = 137; 51%), followed by Asian (n = 91; 34%). After adjustment, Latinx participants had the highest mean MBDA score (40.6 ± 2.1) compared with White participants at (32.8 ± 6.7). Black participants had the second highest mean MBDA score, followed by Asian participants (36.3 ± 5.3, 36.0 ± 2.7, respectively), although neither were significantly different from White participants. The trends observed for the CDAI and DAS28-ESR were similar to those for the MBDA.
conclusionWe found significantly higher disease activity measured by the MBDA and DAS28-ESR in Latinx participants compared with White participants. We also found significantly higher disease activity in Asian participants compared with White participants with the DAS28-ESR. Our findings, although limited by the small number of White participants in the referent group, suggest that RA disease activity measures may be influenced by external factors that have differential impacts by racial and ethnic group.
