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
A next-generation STING agonist MSA-2 is a promising tumor immunotherapy strategy. However, the methods for improving the anti-tumor efficacy of MSA-2 are a lot of effort. We have demonstrated antitumor effect of platinum-modified MSA-2 (MSA-2-Pt) was better than MSA-2. Here, we combined lipid nanoparticles delivering circular IL-23 mRNA (LNP@cIL-23) and MSA-2-Pt strategy, which showed good antitumor efficacy. Firstly, we synthesized a new series of ionizable phospholipids and formulated and optimized an LNP36 for delivering circular IL-23 mRNA. Then, the combination of LNP36@cIL-23 mRNA and MSA-2-Pt induced tumor cell death and immune activation in the tumor with a single i.t. injection. Finally, the combination of LNP36@cIL-23 mRNA and MSA-2-Pt significantly decreased the melanoma B16F10 tumor and prolonged the survival, demonstrating significant anti-tumor effects. This finding provides promising new avenues for STING activation strategies in tumor immunotherapy.
