Healthy dietary patterns, typical healthy foods and risk of endometrial cancer: a systematic review and meta-analysis of observational studies.
Synthesis in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Previous observational studies have investigated the associations between adherence to healthy dietary patterns and endometrial cancer risk; however, pooled quantitative evidence synthesizing healthy dietary patterns and typical healthy foods remains limited. Therefore, we conducted this systematic review and meta-analysis to quantitatively synthesize available evidence on healthy dietary patterns, typical healthy foods and endometrial cancer risk. Methods: Studies published up to February 2026 were systematically identified using PubMed, ISI Web of Science, Embase and China National Knowledge Infrastructure (CNKI) databases. Random- effects or fixed-effects models were used to calculate pooled relative risks (RRs) with corresponding 95% confidence intervals (CIs) where appropriate. Heterogeneity across studies was quantified using Cochran's Q test and the I Results: Thirty-five articles with a total of 533,828 participants and 17,758 endometrial cancer cases were included in our analysis. Compared with the lowest intake of healthy dietary patterns, the highest intake was associated with a 22% lower risk of endometrial cancer (RR = 0.78; 95% CI: 0.65- 0.93, Conclusions: This systematic review and meta-analysis showed that high intakes of healthy dietary patterns, vegetables and whole grains were significantly with a lower risk of endometrial cancer. Further studies, particularly well-designed prospective cohort studies, are needed to confirm these findings.
