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
Cutaneous squamous cell carcinoma (CSCC) is a severe malignancy derived from the skin. Circular RNAs (circRNAs) play an important role in the pathological process of many malignant tumors. Moreover, circIFFO1 is reported to be down-regulated in CSCC tissues compared with non-lesional skin tissues. This study aimed to explore the specific role and potential mechanism of circIFFO1 in CSCC progression. Cell proliferation ability was analyzed by 3-(4, 5-dimethylthiazol-2-y1)-2,5-diphenyl tetrazolium bromide (MTT), 5-ethynyl-2'-deoxyuridine (EdU) incorporation, and colony-formation assays. Cell cycle progression and apoptosis were detected by flow cytometry. Cell migration and invasion were examined by transwell assays. The interaction between microRNA-424-5p (miR-424-5p) and circIFFO1 or nuclear factor I/B (NFIB) was validated by dual-luciferase reporter, RNA pull-down, and RNA immunoprecipitation (RIP) assays. Xenograft tumor assay and immunohistochemistry (IHC) assay were employed to analyze the tumorigenesis in vivo. CircIFFO1 level was down-regulated in CSCC tissues and cell lines. CircIFFO1 overexpression suppressed the proliferation, migration, invasion, and promoted apoptosis of CSCC cells. CircIFFO1 acted as a molecular sponge for miR-424-5p. The anti-tumor effects mediated by circIFFO1 overexpression in CSCC cells could be reversed by miR-424-5p overexpression. miR-424-5p interacted with the 3' untranslated region (3'UTR) of Nuclear Factor I/B (NFIB). miR-424-5p knockdown suppressed the malignant behaviors of CSCC cells, and NFIB knockdown counteracted the anti-tumor effects of miR-424-5p absence in CSCC cells. Additionally, circIFFO1 overexpression restrained xenograft tumor growth in vivo. CircIFFO1 suppressed the malignant behaviors of CSCC by mediating the miR-424-5p/NFIB axis, which provided new insights into the pathogenesis of CSCC.
