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

PMN leukocytes are the most abundant leukocytes in the circulation and play an important role in host defense. PMN leukocyte recruitment and inflammatory responses at sites of infection are critical components in innate immunity. Although inflammation and coagulation are known to have bidirectional relationships, little is known about the interaction between PMN leukocytes and coagulation factors. Coagulation FXI participates in the intrinsic coagulation pathway upon its activation, contributing to hemostasis and thrombosis. We have shown previously that FXI-deficient mice have an increased survival and less leukocyte accumulation into the peritoneum in severe polymicrobial peritonitis. This result suggests a role for FXI in leukocyte trafficking and/or function. In this study, we characterized the functional consequences of FXIa binding to PMN leukocytes. FXIa reduced PMN leukocyte chemotaxis triggered by the chemokine, IL-8, or the bacterial-derived peptide, fMLP, perhaps as a result of the loss of directed migration. In summary, our data suggest that FXIa modulates the inflammatory response of PMN leukocytes by altering migration. These studies highlight the interplay between inflammation and coagulation and suggest that FXIa may play a role in innate immunity.
