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

Antibody affinity maturation occurs in the germinal center (GC), a highly dynamic structure that arises upon antigen stimulation and recedes after infection is resolved. While the magnitude of the GC reaction is highly fluctuating and depends on antigens or pathological conditions, it is unclear whether GCs are assembled ad hoc in different locations or in preexisting niches within B cell follicles. We show that follicular dendritic cells (FDCs), the essential cellular components of the GC architecture, form a predetermined number of clusters. The total number of FDC clusters is the same on several different genetic backgrounds and is not altered by immunization or inflammatory conditions. In unimmunized and germ-free mice, a few FDC clusters contain GC B cells; in contrast, immunization or autoimmune milieu significantly increases the frequency of FDC clusters occupied by GC B cells. Excessive occupancy of GC niches by GC B cells after repeated immunizations or in autoimmune conditions suppresses subsequent antibody responses to new antigens. These data indicate that the magnitude of the GC reaction is restricted by a fixed number of permissive GC niches containing preassembled FDC clusters. This finding may help in the future design of vaccination strategies and in the modulation of antibody-mediated autoimmunity.
