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
Background: Tuberculosis, caused by Mycobacterium tuberculosis (Mtb), remains one of the leading causes of death among infectious diseases. Enhancing the ability of anti-tuberculosis drugs to eradicate Mycobacterium tuberculosis within host cells remains a significant challenge. Methods: A mannosamine-modified nanoparticle delivery system was developed using poly(lactic-co-glycolic acid) (PLGA) copolymers to enhance the targeted delivery of rifapentine (RPT) to macrophages. D-mannosamine was conjugated to PLGA-polyethylene glycol (PLGA-PEG) copolymers through EDC/NHS coupling chemistry, and the resultant RPT-MAN-PLGA-PEG nanoparticles (NPs) were prepared through a combination of phacoemulsification and solvent evaporation methods. The physicochemical properties, toxicity, in vitro drug release profiles, stability, cellular uptake, and anti-TB efficacy of the NPs were systematically evaluated. Results: The RPT-MAN-PLGA-PEG NPs had a mean particle size of 108.2 ± 7.2 nm, with encapsulation efficiency and drug loading rates of 81.2 ± 6.3% and 13.7 ± 0.7%, respectively. RPT release from the NPs was sustained for over 60 hours. Notably, the phagocytic uptake of the MAN-PLGA NPs by macrophages was significantly higher compared to PLGA-PEG NPs. Both NPs improved pharmacokinetic parameters without inducing significant organ toxicity. The minimum inhibitory concentration for the NPs was 0.047 μg/mL, compared to 0.2 μg/mL for free RPT. Conclusion: The engineered RPT-MAN-PLGA-PEG NPs effectively enhanced macrophage uptake in vitro and facilitated the intracellular clearance of Mtb. This nanoparticle-based delivery system offers a promising approach for improving the precision of anti-TB therapy, extending drug release, optimizing pharmacokinetic profiles, augmenting antimicrobial efficacy, and mitigating drug-related toxicities.
