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
Hybrid gold nanoparticles (AuNPs) are defined as a combination of organic and inorganic materials used as nanocarriers in the drug delivery system to enhance the performance of the drugs. Methods to fabricate the hybrid AuNPs such as double emulsion and nanoprecipitation require several steps and are inconsistent in their physicochemical characteristics limiting their application in drug delivery. The electrospray method has become a powerful tool for fabricating nanoparticles due to its simplicity, rapidity and consistency. Hence, this study aims to evaluate the performance of hybrid AuNPs prepared by two different methods; double emulsion and electrospray including the physicochemical characteristics, drug release profile and in vitro cytotoxicity. Hybrid AuNPs were prepared using double emulsion and electrospray methods. Then, the formed particles' hydrodynamic size, polydispersity index (PDI) and zeta potential were characterised using a Zetasizer Nano ZS. Furthermore, the drug release kinetics and cytotoxicity effects were evaluated using the dialysis method and the MTT assay. Hybrid AuNPs formed by the electrospray method (HAES) exhibit smaller particle sizes at 147.00 ± 10.4 nm with a PDI value of 0.35 ± 0.01 and zeta potential of -31.5 ± 2.6 compared to hybrid AuNPs formed using double emulsion methods (HADE) which exhibit larger particle sizes of 287.47 ± 1.87 nm with PDI value of 0.25 ± 0.09 and zeta potential of -23.30 ± 0.6. This study suggests that HAES prevent burst effects during drug release due to polymer composition changes under different temperatures that can enhance the drug delivery system.
