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
Spirochetes of the Borrelia burgdorferi sensu lato complex are the causative agent of Lyme borreliosis, a tick-borne infectious disease primarily affecting the skin, nervous system, and joints. During infection, macrophages and dendritic cells are the first immune cells to encounter invading borreliae. Phagocytosis and intracellular processing of Borrelia by these cells is thus decisive for the eventual outcome of infection. Phagocytic uptake of Borrelia by macrophages proceeds preferentially through coiling phagocytosis, which is characterized by actin-rich unilateral pseudopods that capture and enwrap spirochetes. Actin-dependent growth of these pseudopods necessitates de novo nucleation of actin filaments, which is regulated by actin-nucleating factors such as Arp2/3 complex. Here, we demonstrate that, in addition, also actin-regulatory proteins of the formin family are important for uptake of borreliae by primary human macrophages. Using immunofluorescence, live-cell imaging, and ratiometric analysis, we find specific enrichment of the formins FMNL1 and mDia1 at macrophage pseudopods that are in contact with borreliae. Consistently, small interfering RNA (siRNA)-mediated knockdown of FMNL1 or mDia1 leads to decreased formation of Borrelia-induced pseudopods and to decreased internalization of borreliae by macrophages. Our results suggest that macrophage coiling phagocytosis is a complex process involving several actin nucleation/regulatory factors. They also point specifically to the formins mDia1 and FMNL1 as novel regulators of spirochete uptake by human immune cells.
