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
Purpose: The differential diagnosis of parathyroid carcinoma (PC) or parathyroid adenoma (PA) in parathyroid tumors is crucial for their treatment and prognostic outcomes. We have reported previously that exosomal miR-27a-5p is different in PC or PA, although there are no published studies on a large number of samples, with the role of miR-27a-5p in regulating the effects of PC progression remaining unknown. The current study was designed to investigate the differential expression pattern of exosomal miR-27a-5p in both PC and PA and its relationship with clinicopathologic features, with the aim of further investigating the effect of PC at the cellular level. Methods: The miRNA profiles of serum exosomes from 9 PC and 9 PA patients were evaluated using high-throughput sequencing. The differential expression of exosomal miR-27a-5p was detected in 29 PC and 36 PA patients. We also evaluated the diagnostic efficacy of exosomal miR-27a-5p to identify PC or PA and examined its correlation with the clinicopathologic features of PC. Primary PC cells were obtained by primary cell culture, while the effect of exosomes on PC cell apoptosis was investigated using miR-27a-5p mimic transfection and exosome mixed culture. Finally, the possible target gene of miR-27a-5p, PIK3CA, was identified using a dual-luciferase assay. Results: Exosomal miR-27a-5p differed significantly in PC and PA and was upregulated in PC with good diagnostic efficacy. Exosomal miR-27a-5p was also associated with T-staging of PC. miR-27a-5p inhibited PC cell apoptosis, an action that may be related to its target gene PIK3CA. However, the specific mechanism of this inhibition requires further exploration. Conclusions: The exosomal miR-27a-5p assay is a noninvasive liquid biopsy method that provides an important reference for the timely and accurate identification and treatment of PC. Studies to reveal the mechanism of miR-27a-5p regulation in PC progression are of great significance to improve the current prognostic status of the tumor.
