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
Introduction: Neutrophil Extracellular Traps (NETs) are vital for innate immunity, playing a key role in controlling pathogen and biofilm proliferation. However, excessive NETosis is implicated in autoimmunity, inflammatory and neoplastic diseases, as well as thrombosis, stroke, and post-COVID-19 complications. Managing NETosis, therefore is a significant area of ongoing research. Herein, we have identified a peptide derived from HMGB1 that we have modified via a point mutation that is referred to as mB Box-97. In our recent study in a murine lung infection model, mB Box-97 was shown to be safe and effective at disrupting biofilms without eliciting an inflammatory response typically associated with HMGB1. Here we show that the lack of an inflammatory response of mB Box-97 is in part due to the inhibition of NETosis of which we investigated the mechanism of action. Methods: mB Box-97's anti-NETosis activity was assessed using human neutrophils with known NET inducers PMA, LPS, or Ionomycin. Additionally, mB Box-97's binding to Protein Kinase C (PKC), in addition to downstream effects on NADPH oxidase (NOX) activation, Reactive Oxygen Species (ROS) generation and thereby NETosis were assessed. Results: mB Box-97 significantly inhibited NETosis regardless of the type of induction pathway. Mechanistically, mB Box-97 inhibits PKC activity likely through direct binding and thereby reduced downstream activities including NOX activation, ROS production and NETosis. Conclusions: mB Box-97 is a promising dual acting therapeutic candidate for managing NET-mediated pathologies and resolving biofilm infections. Our results reveal that PKC is a viable target for NETosis inhibition independent of NET inducer and worthy of further study. These findings pave the way for a novel class of therapeutics aimed at controlling excessive NETosis, potentially offering new treatments for a range of inflammatory and immune-related diseases.
