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
OBJECTIVE AND
designParacoccin (PCN), a lectin expressed by Paracoccidioides brasiliensis (Pb), is known to exert activities on the fungal biology, as well as different immune cells of myeloid origin. The aim of this study was to investigate the direct interaction of the recombinant form of the lectin (rPCN) with neutrophils, a neglected area. MATERIALS OR SUBJECTS: Freshly isolated human neutrophils from healthy donors were used. TREATMENT: Neutrophils were incubated with rPCN in vitro.
methodsAfter the treatment, the production of reactive oxygen species (ROS), DNA release, IL-8, TNF, IFN-γ, IL-10, IL-12p40, TGF-β and IL-1β production, fungicidal ability, apoptosis and de novo protein synthesis was determined.
resultsrPCN was found to induce ROS production as well as DNA release. Using the ROS inhibitor, diphenyleneiodium, both ROS production and DNA release were significantly inhibited. In addition, rPCN was found to induce IL-8 and IL1-β production, inhibit apoptosis and induce de novo protein synthesis. Addition of cycloheximide, a protein synthesis inhibitor, drastically reversed the antiapoptotic effect of rPCN. Finally, the ability to kill Pb yeasts by human neutrophils was significantly increased after rPCN stimulation.
conclusionsrPCN can alter the biology of human neutrophils increasing their fungicidal ability. Moreover, the ability of rPCN to increase DNA release and to induce suppression of neutrophil apoptosis occurs by a ROS- and de novo protein synthesis-dependent mechanism, respectively.
