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
objectivesPercutaneous coronary intervention (PCI) is one of the most important treatments for coronary artery disease (CAD). However, in-stent restenosis (ISR) after PCI is a serious complication without effective measures for prevention and treatment. This study aims to investigate the Ras-related protein 1A (Rap1A) level in ISR patients and in the tumor necrosis factor-α (TNF-α)-induced inflammatory injury model of human umbilical vein endothelial cells (HUVECs), to explore the role of Rap1A in regulating TNF-α-induced inflammation in HUVECs and to provide a new potential target for ISR prevention and treatment.
methodsA total of 60 CAD patients, who underwent PCI between December 2020 and July 2022 from the Department of Cardiovascular Medicine of Xiangya Hospital, Central South University, and re-examined coronary angiography (CAG) 1 year after the operation, were included. After admission, 27 patients were diagnosed with ISR and 33 patients were diagnosed with non-in-stent restenosis (non-ISR) according to the CAG. Clinical data were collected, and the plasma Rap1A level was determined by enzyme linked immunosorbent assay (ELISA). In cell experiments, an inflammatory injury model was established with TNF-α treatment (10 ng/mL, 24 h) in HUVECs. The mRNA and protein expression levels of
resultsCompared with the non-ISR patients, a higher proportion of ISR patients had a history of smoking (
conclusionsThe plasma Rap1A level was significantly elevated in patients with ISR, suggesting that Rap1A may be a potential biomarker for predicting ISR. In the TNF-α- induced HUVECs inflammatory injury model, the expression level of Rap1A was increased. The level of TNF-α-induced endothelial cell inflammation was decreased after inhibition of Rap1A expression, suggesting that Rap1A may be a potential target for the treatment of endothelial cell inflammation in ISR.
