Article in Journal of bone oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Background: Hypoxia is a key characteristic of osteosarcoma (OS). Increasing data suggested that circular RNA (circRNAs) were involve in the progression of cancers and the regulation of hypoxia, including OS. This study aims to examine the biological mechanism of circRNA cytochrome P450 family 51 subfamily A member 1 (circCYP51A1) in OS under hypoxia. Methods: The expression levels of circCYP51A1, microRNA-490-3p (miR-490-3p) and kruppel-like factor 12 (KLF12) were detected by quantitative real-time polymerase chain reaction (qRT-PCR) in OS tissues and cells. Cell proliferation, migration and invasion were determined by colony formation assay and transwell assay. Lactate production and glucose consumption in OS cells were measured by using lactate assay kit and glucose assay kit, respectively. Western blot assay and immunohistochemistry assay were used to test protein levels. The associated relationship between miR-490-3p and circCYP51A1 or KLF12 was predicted using Starbase or DIANA online database and verified by dual-luciferase reporter assay. The xenograft model was used to explore the role of circCYP51A1 Results: CircCYP51A1 and KLF12 expression were dramatically increased, whereas miR-490-3p was decreased in OS cells under hypoxia condition. Deficiency of circCYP51A1 hindered hypoxia-induced cell proliferation, migration, invasion and glycolysis in OS cells. CircCYP51A1 enhanced KLF12 expression by sponging miR-490-3p. MiR-490-3p inhibitor weakened the inhibition effect of circCYP51A1 knockdown on the progression of OS under hypoxia. Besides, overexpression of miR-490-3p inhibited cell progression of OS under hypoxia condition, while the effects were attenuated by KLF12 overexpression. Importantly, knockdown of circCYP51A1 inhibited tumor growth Conclusion: CircCYP51A1 mediated cell proliferation, migration, invasion and glycolysis by regulating miR-490-3p/KLF12 axis in OS cells under hypoxia condition.
