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

B lymphocyte recirculation through lymph nodes (LNs) requires crossing endothelial barriers and chemoattractant-triggered cell migration. Here we show how LN anatomy and chemoattractant receptor signaling organize B lymphocyte LN trafficking. Blood-borne B cells predominately used CCR7 signaling to adhere to high endothelial venules (HEVs). New B cell emigrants slowly transited the HEV perivenule space, and thereafter localized nearby, avoiding the follicle. Eventually, the newly arrived B cells entered the basal portion of the follicle gradually populating it. In contrast, newly arriving activated B cells rapidly crossed HEVs and migrated toward the lymph node follicle. During their LN residency, recirculating B cells reacquired their sphingosine-1 phospate receptor 1 (S1P1) receptors and markedly attenuated their sensitivity to chemokines. Eventually, the B cells exited the LN follicle by entering the cortical lymphatics or returning to the paracortical cords. Upon entering the lymph, the B cells lost their polarity, down-regulated their S1P1 receptors, and subsequently strongly up-regulated their sensitivity to chemokines. These results are summarized in a model of homeostatic trafficking of B cells through LNs.
