Association between transoesophageal echocardiography monitoring indicators and the incidence of postoperative acute kidney injury in coronary artery bypass grafting: a study protocol for a prospective multicenter cohort study.
Article in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05139108 (The Association Between Transesophageal Echocardiography Monitoring and the Incidence of Postoperative Acute Kidney Injury in Coronary Artery Bypass Grafting：a Prospective Observational Study), which is not on this map.

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.

Abstract
introductionPrevious studies on transoesophageal echocardiography in coronary artery bypass grafting mainly focused on whether to change the surgical plan rather than improve the clinical prognosis. Currently, there are sparse studies on the relationship between transoesophageal echocardiography indicators and the prognosis of patients undergoing coronary artery bypass grafting. The primary aim of this study is to explore the association between transoesophageal echocardiography monitoring indicators the respiratory variability of inferior vena cava diameter, tricuspid annular plane systolic excursion and the incidence of acute kidney injury in coronary artery bypass grafting patients. METHODS AND ANALYSIS: We designed this prospective multicenter cohort study, which included approximately 150 adult patients (≥18 years) undergoing elective coronary artery bypass surgery. Different hospitals will be assessed to obtain information on the prevalence, risk factors, management strategies and outcomes in coronary artery bypass surgery. The cohort will be followed after the coronary artery bypass surgery period, up to 30 days after enrolment. The incidence of postoperative acute kidney injury and baseline data will be presented by descriptive statistics. We will use Freidman inspection and multivariable logistic regression to assess the association between transoesophageal echocardiography monitoring indicators and the incidence of acute kidney injury in coronary artery bypass grafting patients. ETHICS AND DISSEMINATION: The study has been approved by the ethics committee of Shandong Provincial Qianfoshan Hospital, China (approval number: YXLL-KY-2021(067)). This is an observational study that poses no risk to the patients. All participants will obtain informed consent according to the ethics committee before patient enrolment. Funding sources will have no influence on data handling, analyses or writing of the manuscript. The article is planned for submission in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT05139108.
