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
objectiveTo investigate the effect of exosomes derived from Epstein-Barr virus (EBV)-positive nasopharyngeal carcinoma (NPC) cells on lymphangiogenesis and lymph node metastasis of NPC.
methodsExosomes from NP69 cells and EBV-positive HK1 (HK1-EBV) cells were obtained by ultracentrifugation and identified by Western blotting and nanoparticle tracking analysis. Dio dye phagocytosis test was performed to observe exosome uptake by lymphatic endothelial cells. Lymphatic endothelial cells were treated with exosomes from nasopharyngeal epithelium (NP69), HK1-EBV, and C666-1 cells or exosome-free supernatant of HK1-EBV and C666-1 cells, and tube formation and migration of the cells were observed. In a nude mouse model of popliteal lymph node metastasis of NPC, the effects of normal saline, NP69 cell-derived exosomes, HK1-EBV cell-derived exosomes, exosome-free supernatant of HK1-EBV cells, and HK1-EBV exosome-free supernatant protein on lymphangiogenesis and lymph node metastasis of the tumor were observed.
resultsThe exosomes obtained by ultracentrifugation contained abundant exosome-specific proteins and showed a normal size range. The exosomes from NPC cells and NP69 cells could be taken up by lymphatic endothelial cells. Compared with the blank control and exosomes form NP69 cells, exosomes derived from HK1-EBV and C666-1 cells significantly promoted tube formation and migration of lymphatic endothelial cells (
conclusionsExosomes from EBV-positive NPC cells can significantly promote lymphangiogenesis and lymph node metastasis of NPC.
