Effect of dietary and lifestyle intervention in pregnant women: randomized clinical trial.
Trial report in Revista de saude publica, 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
objectiveTo evaluate the intra- and between-group (control and intervention) effect of counseling during pregnancy on pregnant women's food consumption and physical activity.
methodsThis randomized, parallel, two-arm clinical trial was carried out in primary health care in a Brazilian municipality from 2018 to 2021. Adult pregnant women with pre-gestational overweight (n = 350) were randomly assigned to the control or intervention groups. The intervention consisted of three counseling sessions based on the NOVA food classification system and encouragement toward physical activity. Then, 24-hour dietary records were obtained, and physical activity was assessed using a structured questionnaire. The Wilcoxon test was used for intra-group differences between assessments and the Mann-Whitney test, for differences between groups.
resultsWomen in the control group consumed less minimally and unprocessed foods (%E) (Δ = -4.08; -13.58 to 4.34; p = 0.006) and more ultra-processed foods (%E) (Δ = 3.74; -5.86 to 12.86; p = 0.009), with no difference between groups. The intervention group showed an increase in commuting-related physical activity (min/week) between assessments (Δ = 9.00; -30.00 to 70.00; p = 0.02), with no difference between groups. The other parameters showed no differences.
conclusionsThe intervention failed to affect outcomes. However, intragroup changes showed that the control consumed less minimally and unprocessed foods and more ultra-processed foods and the intervention group increased their commuting-related physical activities.
