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
purposeThe beneficial effects of Mediterranean Diet (MD) during pregnancy are well established. However, validated tools adapted to assess adherence to the MD during pregnancy and across different cultural contexts remain limited. This study aimed to translate, cross-culturally adapt, and validate an Italian version of the pregnancy-adapted Mediterranean Diet Adherence Screener (ITpreg-MEDAS), derived from the original Spanish preg-MEDAS questionnaire. We hypothesized that the ITpreg-MEDAS would show adequate construct validity and would be associated with markers of diet quality during pregnancy.
methodsThe preg-MEDAS is a 17-item questionnaire designed to assess adherence to the MD among pregnant women. The Italian version was developed following a six steps process in accordance with established methodological guidelines: forward translation, synthesis I, blind-back translation, synthesis II, pre-testing, and validation. Psychometric properties were evaluated by assessing internal consistency, test-retest reliability, and construct validity, in a sample of Italian pregnant women.
resultsThe preg-MEDAS was translated and cross-cultural adapted, requiring some semantic revisions. All 25 Italian pregnant women involved in the pre-testing in pre-testing found it clear and comprehensible. A total of 116 Italian pregnant women participated in the validation phase, with a mean ITpreg-MEDAS score of 7.2 ± 2.5 out of 17, indicating medium adherence to the MD. Reliability was confirmed by good test-retest correlation (r = 0.756) and acceptable internal consistency (Cronbach's α = 0.623).
conclusionThe ITpreg-MEDAS is a reliable and valid Italian version of the preg-MEDAS questionnaire, providing a simple tool to assess adherence to the Mediterranean Diet during pregnancy in both clinical practice and research.
