Effects of Mediterranean diet during pregnancy on the onset of overweight or obesity in the offspring: a randomized trial.
Trial report in International journal of obesity (2005), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 6 papers.
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/
objectivesThe PREMEDI study was designed to assess the efficacy of nutritional counseling aimed at promoting Mediterranean Diet (MD) during pregnancy on the incidence of overweight or obesity at 24 months in the offspring.
methodsPREMEDI was a parallel-arm randomized-controlled trial. 104 women in their first trimester of pregnancy were randomly assigned in a 1:1 ratio to standard obstetrical and gynecological care alone (CT) or with nutritional counseling promoting MD. Women enrolled in the MD arm were provided with 3 sessions of nutritional counseling (one session per trimester). The main outcome was the proportion of overweight or obesity among the offspring at the age of 24 months. Maternal MD-adherence and weight gain during pregnancy were also evaluated. Lastly, the evaluation of epigenetic modulation of metabolic pathways in the offspring was analyzed in cord blood.
resultsFive women in the MD arm and 2 in the CT arm were lost to follow-up, so a total of 97 completed the study. At 24 months, children of MD mothers were less likely to have overweight or obesity than those of the CT mothers (6% vs. 30%, absolute risk difference = -24%, 95% CI -38% to -9%, p = 0.003, number needed to treat 4, 95% CI 2 to 12, per-protocol analysis). A significantly higher increase of MD-adherence during the trial was observed in the MD arm compared to the CT arm. A similar body weight gain at the end of pregnancy was observed in the two arms. The mean (SD) methylation rate of the leptin gene in cord blood was 30.4 (1.02) % and 16.9 (2.99) % in the MD and CT mothers, respectively (p < 0.0001).
conclusionsMD during pregnancy could be an effective strategy for preventing pediatric overweight or obesity at 24 months. This effect involves, at least in part, an epigenetic modification of leptin expression.
