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
Hepatocellular carcinoma (HCC) presents a significant therapeutic challenge, necessitating novel approaches beyond conventional treatments. This study investigates the combined cytotoxic effects of nano-titanium dioxide (nano-TiO₂), copper (II) phthalocyanine (CuPc), and copper (II) phthalocyanine-modified nano-TiO₂-(nano-TiO₂/Pc) on HepG2 hepatocellular carcinoma cells using sonodynamic therapy (SDT), photodynamic therapy (PDT), and sonophotodynamic therapy (SPDT). The results show that individual treatments with nano-TiO₂ or CuPc alone did not induce significant cytotoxicity. However, when combined with SDT or PDT, a noticeable decrease in cell viability was observed. Strikingly, SPDT combined with nano-TiO₂/Pc demonstrated the most significant cytotoxic effect, achieving up to 83.80% apoptosis in HepG2 cells. This was associated with a marked reduction in Bcl-2 protein levels and an increase in cleaved caspase-3, cleaved caspase-9, cytochrome-c (cyt-c), and Bax indicating the activation of both intrinsic and extrinsic apoptotic pathways. Furthermore, SPDT-nano-TiO₂/Pc significantly increased oxidative stress, as evidenced by decreased levels of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH), along with elevated levels of malondialdehyde (MDA). These findings suggest that phthalocyanine-mediated SPDT effectively enhances mitochondrial apoptosis and disrupts the tumor cytoplasmic membrane, highlighting the potential of combining SDT and PDT with nano-TiO₂/Pc as a promising strategy for cancer treatment.
