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
backgroundThe Wnt/β-catenin pathway is frequently activated in hepatocellular carcinoma (HCC); thus, it is considered a potential target for novel therapies. Safranal (SAF), a natural product, is reputed for its antitumor and antioxidant activities. Gold nanoparticles (AuNPs) exhibit unique physicochemical properties, they can carry and transport drugs to the tumor as they can passively accumulate within the tumor. The current study aims to evaluate SAF and SAF-AuNPs antitumor effect in HCC model via targeting the Wnt pathway and to evaluate the ability of SAF-AuNPs and Doxorubicin-gold nanoparticles (DOX-AuNPs) in ameliorating DOX chemo-resistance in HCC and enhancing its therapeutic index to reduce unwanted side effects.
resultsSAF significantly attenuated the Wnt/β-catenin pathway, which down-regulated the proliferation and tumor angiogenesis. SAF decreased significantly Wnt-3a, β-catenin, Cyclin D1 VEGF and MMP-9. Developing SAF-AuNPs enhanced the antitumor activity of SAF against HCC. Furthermore, SAF-AuNPs enhanced DOX-AuNPs antitumor activity and lowered multi-drug resistance (MDR) protein level, which attenuates DOX chemo-resistance.
conclusionsWe conclude that SAF and SAF-AuNPs are promising treatments for HCC. They have promising antitumor activity in addition to the ability to attenuate DOX chemo-resistance, so, the desired therapeutic effect may be obtained with minor doses and lowering the side effects.
