About this study
Official title: A Prospective Cohort Study of Predictors and Prognostic Factors on the Acute Ischemic Stroke
Through 5 years continuous observation of acute ischemic stroke patients in Neurology Department of Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, clinical data about emergency treatment (neurological score, examination and treatment), medical data after admission (neurological score, inspection, examination and treatment) and long-term prognosis (neurological score) was collected. The outcomes were set as the score scale, all blood test index and examination index of the research objects at specific period after illness. Through statistical analysis and comparison of different in-hospital clinical data in predicting the outcome of the patients, our study will provide more evidence-based solutions for the treatment and prediction of acute ischemic stroke.
Read the detailed description
The research is designed as registrated, prospective, open-labeled, blind-endpoint, and the research objects are continuously recorded. The final subgroups are blind to neurological evaluators, data inputers and statisticians.
The research is a continuous observational exploratory study. All patients with ischemic stroke admitted to Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology from April 1, 2017 to December 31, 2021 will be included. According to the current situation, it is expected to enroll approximately 5000 of eligible patients for long-term follow-up observation.
We'll use multiple linear regression analysis model to study factors and confounding factors and their interaction. And we will control the confounding factors, and make a quantitative description of the relationship between factors and outcome variables.
Missing cases will be treated as censored values, and the ratio of missing cases will be recorded. All samples will be analyzed by Intent-to-Treat (ITT) analysis. In the analysis, if the results are statistically significant, the missing cases in the exposed group will be deleted, and the missing cases in non-exposure group be added. If the results are still statistically significant, then the missing cases are defined as not affecting the analysis results.
If the heterogeneity of data is large, the objects will be analyzed in subgroups according to age or sex.
If the missing rate is greater than 20%, it is necessary to analyze the sensitivity of the whole sample.

Questions about this trial
What is this clinical trial studying?
An observational study of Ischemic Stroke, run by Tongji Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 7 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Limited number of participants enrolled.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Modified Rankin Scale scores (time frame: Change from Baseline mRS score at 24 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03122002, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Dec 2022.
