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
objectiveThe current study evaluated the expression profile and explored the therapeutic implications of Jagged 1 in human thyroid cancer. MATERIALS AND
methodsThis experimental study was conducted in 60 paired specimens of papillary thyroid and adjacent normal tissues. Gene expression was determined by quantitative real time polymerase chain reaction (qRT-PCR) and western blotting. Transfection of cancer cells was performed by using Lipofectamine 2000. The cell proliferation of PTC cells was estimated by MTT assay. Clonogenic assay was performed for analysis of colony forming potential of cancer cells. The apoptosis of PTC cells was studied by using AO/EB and Annexin V-FITC/PI staining methods. Flow cytometry was done to analyze the cell cycle phase distribution of cancer cells. Migration and invasion PTC cells were determined respectively with the wound-healing and transwell assays. The impact of Jagged 1 silencing was investigated
resultsWe found significant (P<0.05) upregulation of Jagged 1 in human thyroid cancer. Silencing of Jagged 1 caused significant (P<0.05) reduction in proliferation and colony formation of MDA-T68 cells. The inhibitory effects of Jagged 1 silencing were found to be due to the induction of apoptosis. We also found enhancement of Bax and repression of Bcl-2 protein levels in MDA-T68 cells. Wound healing assay indicated significant (P<0.05) inhibition of cell migration of MDA-T68 thyroid cancer cells. Additionally, we found that invasion of the thyroid cancer cells was reduced by 55% upon silencing of Jagged 1. Moreover, Jagged 1 silencing was found to cause inhibition of the Notch intracellular domain (NICD) and Notch target gene, Hes-1 expression. Finally, Jagged 1 silencing inhibited the xenografted tumors
conclusionThe findings suggest that Jagged 1 regulates the development of thyroid cancer that may act as a therapeutic target for managing thyroid cancer.
