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
The aim of this research was to investigate the impact of periplocin (PPLN) on oxaliplatin (OXA) resistance in hepatocellular carcinoma (HCC) cells and offer insights for improving clinical treatment of HCC. The IC50 value of HCC cell lines against OXA was detected by the CCK-8 assay, and an OXA-resistant HepG2 cell line (HepG2/OXA) was constructed. THP-1 cells were induced into M1 or M2 macrophages, and M2 macrophage-conditioned medium (M2-CM) was prepared. M1 and M2 macrophage polarization were detected using RT-qPCR and flow cytometry. CCK-8, EdU staining, clone formation assay, flow cytometry, and western blotting were used to assess the proliferation and apoptosis of HepG2/OXA cells treated with PPLN and M2-CM. Additionally, a nude mouse subcutaneous graft tumor model was constructed. PPLN enhanced the sensitivity of HepG2/OXA cells to OXA, reduced their clone-forming ability, and promoted their apoptosis. Notably, PPLN hindered M0 macrophage polarization to M2 macrophages, while M1 polarization remained unaffected. The proliferation-inhibiting and apoptosis-promoting effects of OXA+PPLN on HepG2/OXA cells were significantly attenuated by the addition of M2-CM, suggesting that PPLN improves the OXA sensitivity of HepG2/OXA cells by hindering M2 macrophage polarization. Furthermore, PPLN inhibited M2 macrophage polarization and improved the OXA sensitivity of HepG2/OXA cells in vivo. In conclusion, PPLN inhibited the proliferation of HepG2/OXA cells, promoted their apoptosis, and inhibited M2 macrophage polarization both in vivo and in vitro, which in turn enhanced the OXA sensitivity of HepG2/OXA cells.
