Therefore, we carried out this comprehensive systematic review and meta-analysis to analyze the available literature on the associations between healthy dietary patterns and risk and survival of ovarian cancer.<h4>Methods</h4>PubMed, Web of Science, Scopus and China National Knowledge Infrastructure (CNKI) were comprehensively searched for the relevant articles published from databases inception to October 2024. According to heterogeneity, the pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated for the highest versus the lowest categories of healthy dietary patterns in relation to ovarian cancer riskFrontiers in nutrition1681162https://www.ebi.ac.uk/biostudies/studies/S-EPMC12554572biostudies-literatureHealthy dietary patterns and ovarian cancer risk and survival: a systematic review and meta-analysis.PMC12554572Chen JZhao KXu YfalseHealthy dietary patterns and ovarian cancer risk and survival: a systematic review and meta-analysis.<h4>Background</h4>Studies investigating the associations between healthy dietary pattern and risk and survival of ovarian cancer have been limited and inconsistent.
