Decreased IgD- CD27- double negative B cells in Sjögren's disease correlated with disease activity index.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Double negative (DN) B cells, defined as CD27-IgD- B cells, are increased in older healthy individuals as well as in patients with certain diseases. However, the relationship between DN B cells and Sjögren's disease (SjD) in newly diagnosed patients remains unclear. Seventy SjD patients and thirty-six healthy controls (HCs) were recruited in this study. Peripheral blood B cell subsets were analyzed using flow cytometry. The percentage and absolute count of DN B cells were significantly lower in SjD patients compared to HCs (p = 0.000 and p = 0.007, respectively). Patients with medium to high disease activity, defined by an EULAR Sjögren Syndrome Disease Activity Index (ESSDAI) score ≥ 5, exhibited lower DN B cell levels compared to those with low disease activity (ESSDAI score < 5, p = 0.029 and p = 0.000, respectively). Moreover, lower DN B cell percentages were associated with glandular involvement (p = 0.039) and neutropenia (p = 0.034). Regression analysis revealed a negative correlation between DN B cells and SjD disease activity (B=-0.240, 95% CI:-0.468 to -0.013, p = 0.039). Additionally, DN B cells showed weak negative correlation with the percentage of total B cells (r=-0.266, p = 0.026). This study demonstrates that DN B cells are decreased in SjD, particularly in patients with glandular involvement and high disease activity. Moreover, the inverse correlation between DN B cells and total B cells suggested that DN B cells may play a role in the pathogenesis of SjD.
