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
objectivesA study was conducted to investigate the molecular mechanism of chromodomain helicase/ATPase DNA binding protein 1-like gene (CHD1L) influencing the invasion and metastasis of tongue squamous cell carcinoma and to provide a new target for clinical inhibition of invasion and metastasis of tongue squamous cell carcinoma.
methodsUalcan website was used to analyze the expression of CHD1L in normal epithelial tissue and primary head and neck squamous cell carcinoma and to analyze the effect of lymph node metastasis on the expression of CHD1L in tissues with head and neck squamous cell carcinoma. The relationship between CHD1L expression and the survival rate of patients with head and neck squamous cell carcinoma was tested by the GEPIA website. Western blot was used to quantify the levels of CHD1L protein in human tongue squamous cell carcinoma CAL27 and immortalized human skin keratinocyte cell HaCaT. After knocking down CAL27 in human tongue squamous cell carcinoma cells with an RNA interference plasmid, the cells were designated as SiCHD1L/CAL27 and Scr/CAL27. Western blot was utilized to detect the expression of CHD1L in each group of cells. The change in CAL27 cell proliferation ability was tested by EdU proliferation test after CHD1L knockdown. The change of cell migration ability of each group cells was tested through the wound healing assay. Western blot was used to detect epithelial-mesenchymal transition (EMT) marker E-cadherin and Vimentin protein expression levels.
resultsUalcan database showed that the expression of CHD1L in primary head and neck squamous cell carcinoma tissues was higher than in normal epithelial tissues and in head and neck squamous cell carcinoma tissues with lymph node metastasis. GEPIA website analysis showed that the overall survival rate of patients with head and neck squamous cell carcinoma with high expression of CHD1L was significantly lower than that of patients with low expression. Western blot results showed that CHD1L expression in human tongue squamous carcinoma cells CAL27 was higher than that of human normal skin cells HaCaT. CHD1L expression in SiCHD1L/CAL27 cells was much lower than that in Scr/CAL27 cells. Results of EdU proliferation experiments showed the significant reduction in the cell proliferation ability of the SiCHD1L/CAL27 cells. Results of the wound healing experiments showed the reduction in the migration capacity of the SiCHD1L/CAL27 cells. The expression of E-cadherin increased, whereas that of Vimentin decreased, in SiCHD1L/CAL27 cells.
conclusionsCHD1L promoted the EMT, proliferation, migration, and invasion ability of tongue squamous cell carcinoma cells.
