Impact of Mediterranean Diet Adherence in Early Pregnancy on Nausea, Vomiting, and Constipation.
Article in Maternal and child health journal, 2025. 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
objectivesCommon maternal digestive symptoms, such as nausea, vomiting, and constipation during pregnancy, can impair pregnant women's quality of life. The Mediterranean diet (MedDiet), characterized by a high consumption of olive oil, vegetables, fruits, legumes, and grains; moderate fish and dairy intake; and low meat consumption, could alleviate these symptoms. This study aims to study the prevalence of maternal digestive symptoms in the different pregnancy trimesters and to examine the association between baseline MedDiet adherence and the prevalence of maternal digestive symptoms during pregnancy.
methodsA secondary analysis of the Walking Preg_Project trial was conducted in a cohort of adult Spanish pregnant women (N = 237) who provided data about MedDiet adherence and maternal digestive symptoms (nausea, vomiting, constipation) at baseline (12th ), 19
resultsDifferences among MedDiet adherence categories were considerable during pregnancy. Some of the greatest decreases were observed in high adherence to MedDiet in comparison with low MedDiet adherence at 32nd GW vs. 19th GW for the prevalence of nausea (10.0% vs. 18.8%, p < 0.001) and vomiting (5.0% vs. 8.7%, p < 0.001). Constipation remained during pregnancy. There was no significant association between the baseline MedDiet adherence and maternal gastrointestinal symptoms. CONCLUSION FOR PRACTICE: Baseline adherence to the MedDiet was not proven to influence nausea, vomiting, and constipation during pregnancy. For all MedDiet adherence groups, nausea and vomiting prevalence decreased throughout pregnancy, but not constipation.
