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
Multi-drug combination therapy is one of the most effective strategies for the treatment of drug-resistant and advanced tumors. Modern nanodrug delivery systems are crucial for multi-drug combination therapy and gene therapy. However, research on direct injection of RNAi has not yielded significant results. Artificial vectors are emerging as promising delivery systemts for RNA for gene therapy. In this study, a multi-drug therapy system was built based on a biodegradable exosome nano-platform exploiting the protective and low immunogenic properties of exosomes for RNA. This work aimed to accomplish the co-delivery of siRNA and 3-Bromopyruvic acid (3BP) on an exosome nanoplatform, enhancing targeting by coupling cetuximab (CTX) to exosome membranes, resulting in a new nanomedicine Exo@siRNA/3BP-CTX (ERBC) engineered exosomes. The synthesis conditions were optimized to obtain stable, safe, and effective nanomedicines. Successful targeting of tumors with CTX inhibited KRAS oncogene expression and significantly reduced glucose uptake by cancer cells. This enhanced the starvation therapy effect of the energy deprivation agent 3BP, thus promoting excessive autophagy activation in cells and doubling apoptosis. However, ERBC combined with CTX therapy restored cellular chemosensitivity to CTX. These findings indicate that engineered exosomes with dual therapeutic activities is a promising approach for treating refractory KRAS-mutant cancers.
