Folate-targeted gold nanoparticles for doxorubicin delivery in tumor spheroids.
Article in Drug delivery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Targeted drug delivery systems represent a promising strategy for enhancing the efficacy and specificity of cancer therapy. In this study, 35 nm folate-targeted gold nanoparticles are presented as nanoparticle-drug conjugates obtained by anchoring on their surface lipoyl terminating doxorubicin prodrug (proDoxo) releasable at the endolysosomal acidic pH to prevent off-site toxic effects. Colloidal stable nanoparticles with a density of proDoxo up to 1000 molecules/particle and 2 kDa mPEG-SH coating were obtained. At pH 5, Doxo was completely released from the nanoparticles in 5 days while only 13% was released over the same period at pH 7.4. The nanoparticle decoration with folic acid as a targeting agent bestowed nanosystems with selective drug delivery to folate receptor (FR)-overexpressing cancer cells and controlled intracellular release. This led to enhanced cancer cell killing by folated nanoparticles compared to their nontargeted counterparts. Moreover, folated nanoparticles were found to distribute more homogeneously inside KB
