About this study
Official title: Gender Influence on Mortality and Major Morbidity After Pediatric Cardiac Surgery.
Recent studies show an important influence of gender on inflammatory reactions. Cardiac surgery is associated with a major systemic inflammatory response. The investigators want to evaluate the gender influence on morbi-mortality in pediatric cardiac surgery patients.
Read the detailed description
Gender plays an important role in the inflammatory response. This is due to hormonal influences, but also different genetic regulation of pro-inflammatory cytokines, as nuclear facto kapp B. it is also know that cardiac surgery, especially under cardiopulmonary bypass, is associated with a major inflammatory response. This response is even more marked in pediatric cardiac surgery. The investigators hypothesise that there is a gender influence on mortality and major morbidity in paediatric patients undergoing cardiac surgery. The investigators will do a retrospective cohort study, analysing the local database of all paediatric cardiac surgery cases from jan 2006 to dec 2019. Primary outcome will be any difference in mortality and /or major morbidity according to gender.
Statistical analysis:
The investigators will use a propensity score on 11 pre-operative variables clinically judged relevant. Both group will be matched until a absolute standardised difference < 15% is obtained. This type of matching, contrary to a P value, is independent of sample size. Variables will be presented as mean, standard deviation or percentage for frequency distributions. After propensity score matching, logistic regressions will be performed on binary variables and linear regressions on continuous variables. A Bonferroni correction will be used for multiple comparisons.

The record says: finished, as of the sponsor's last update on 28 Jan 2021. 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 Belgium. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Mortality (time frame: Beginning of the operation until 5 days postop). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 28 Jan 2021; AzTrials last refreshed its copy on 7 Nov 2026.
