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
introductionSorafenib (SOR) is a low-dose multikinase inhibitor that suppresses angiogenesis by blocking vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptors. The aim of the present study was to develop Sorafenib-loaded chitosan (CS) and hyaluronic acid (HA) polyelectrolyte complex nanoparticles (SCH-NP) for triple negative breast cancer (TNBC).
methodsFor TNBC therapy, SCH-NP were formulated and optimized using Central Composite Design (CCD). The prepared SCH-NP were characterized by particle size, zeta potential, Polydispersity index, Fourier Transform Infrared Spectroscopy (FTIR), entrapment efficiency, invitro drug release study, in-vitro and in vivo studies.
resultsSCH-NP were formulated and optimized using CCD. The developed SCH-NP showed particle size of 125 nm, zeta potential of -13.7 mV, PDI value 0.21 and entrapment efficiency of 82.07%. FTIR study confirmed no interaction between drug and polysaccharide. The cumulative release percentage of SOR from SCH-NP was 81.73%. SOR's IC50 value was much larger than, SCH-NP's in both MDA-MB 231 & 4T1 cell lines. After treatment for 18 days, the tumor volumes in mice increased to 447.4 mm
conclusionsThe present study suggests that SCH-NP might be effective for the tumor-targeted delivery of Sorafenib and it might be a suitable nanocarrier for enhancing SOR cytotoxicity in vitro and may be useful for the tumor-targeted delivery of SOR.
