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
The purpose of this study was to investigate the potential of discoidal polymeric particles (DPPs) coated with macrophage membranes as a novel drug delivery system. The study aimed to determine whether these coated particles could reduce phagocytosis, and target specific organs, thereby enhancing drug delivery efficacy. In this study, discoidal polymeric particles (DPPs) were synthesized by a top-down fabrication method serving as the core drug delivery platform. The method involved the fusion of macrophage cell membrane vesicles with DPPs, resulting in macrophage membrane coated DPPs. This process aimed to translocate membrane proteins from macrophages onto the DPPs, rendering them structurally and functionally like host cells. The results of this study showed that macrophage membrane coated DPPs exhibited a threefold reduction in phagocytosis compared to bare DPPs. This reduction in phagocytosis indicated the potential of these coated DPPs to evade immune clearance. Time-lapse microscopy further illustrated the distinct interactions of macrophage membrane coated DPPs with immune cells. Biodistribution studies revealed that these coated particles displayed preferential accumulation in the lungs at early time points, followed by sustained accumulation in the liver. In conclusion, this study demonstrated that macrophage membrane coated DPPs represent a unique and promising strategy for drug delivery. These particles can mimic cell surfaces, reduce phagocytosis, and target specific organs. This opens exciting avenues for improving drug delivery efficacy in diverse therapeutic contexts. These findings advance our understanding of nanomedicine's potential in personalized therapies and targeted drug delivery strategies.
