1 · What the graph read from it

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.

2 · The registry

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

Marginal zone (MZ) B cells bridge innate and adaptive immunity by sensing bloodborne antigens and producing rapid antibody and cytokine responses. When unregulated, MZ B cells are associated with autoimmunity. CD55 is a membrane-bound complement regulator that interferes with complement activation and is another important component of innate and adaptive immunity. MZ B cells express low CD55 in both mice and humans, but the role of CD55 in MZ B cell function is unknown. Using germline knockout (KO) mice, we found that similar numbers of MZ B cells were initially established in 3-wk-old CD55-deficient mice compared with wild-type mice. However, MZ B cells failed to accumulate as mice aged and underwent increased apoptosis independent of alternative complement activation. Following ex vivo stimulation of MZ B cells through TLR9 (Toll-like receptor 9), we observed increased interleukin-6 expression in CD55 KO MZ B cells. In addition, CD55 KO mice exhibited reduced total IgG response following in vivo administration of TLR9 agonist. These findings provide new insights into the role of CD55 in MZ B cell survival and B cell function.
