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
This study investigates the effects of 4-farnesyloxycoumarin (4-FOC)-conjugated NCC/CTAB/CS nanoparticles (NPs) on PANC-1 pancreatic cancer cells, highlighting their cytotoxicity and antioxidant properties. Dynamic light scattering (DLS) analysis revealed a Z-average particle size of 275.68 nm, with a polydispersity index of 0.3020. The mean intensity diameter was 334.68 nm, and the mean volume diameter was 380.97 nm. The zeta potential was recorded at 28.88 ± 12.64 mV, confirming good stability due to electrostatic repulsion. Field emission scanning electron microscopy (FESEM) confirmed the successful conjugation of 4-FOC to the NPs, and Fourier-transform infrared (FTIR) spectroscopy validated the incorporation of functional groups. In contrast, the encapsulation efficiency of 4-FOC was measured at 88.49%. Cytotoxicity assays indicated a significant reduction in PANC-1 cell viability, with an IC50 value of 61.23 µg/mL; in contrast, human dermal fibroblast (HDF) cells exhibited greater resilience, maintaining 92.61 ± 2.33% viability at 100 µg/mL. Apoptotic assays revealed a dose-dependent increase in early and late apoptotic cells, with late apoptosis rising to 54.1% at 81 µg/mL. Gene expression analysis showed significant upregulation of caspase 3 (2.25 ± 0.33), p21 (1.70 ± 0.05), and p53 (2.71 ± 0.29 at 61 µg/mL), underscoring the NPs' role in apoptosis and cell cycle regulation. Additionally, the antioxidant capacity of the NPs was confirmed through ABTS and DPPH radical scavenging assays, achieving 38.82% and 68.25% scavenging activity at the highest concentrations, respectively. These findings suggest that 4-FOC-conjugated NCC/CTAB/CS NPs hold promise as a therapeutic strategy for treating pancreatic cancer.
