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
Current mRNA-LNP systems face challenges in efficient co-delivery of nucleic acid adjuvants, limiting their capacity to elicit robust cellular immunity. To overcome the dissociation limitations of physically admixed CpG in conventional lipid nanoparticles, we developed a covalent conjugation platform that integrates TLR9 agonists with phospholipids via amide bonding. We synthesized a DSPE-CpG conjugate, which exhibited high loading efficiency (97.1%) onto mRNA-LNPs. The immune activation efficacy was evaluated in models encoding SARS-CoV-2 spike protein and HBV antigens. The DSPE-CpG-mRNA LNP system demonstrated enhanced cellular uptake via clathrin-mediated endocytosis, superior lymph node targeting of the adjuvant, and improved antigen expression in vivo. In the SARS-CoV-2 model, it induced high levels of IFN-γ⁺CD8⁺ T cells and elicited higher titers of specific IgG and neutralizing antibodies. In the HBV model, it significantly enhanced antigen-specific CD107a
