Investigating the factors related to the brain executive function change during pregnancy.
Article in BMC pregnancy and childbirth, 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
objectivesSome studies indicate cognitive defects during pregnancy, but the factors affecting these defects have not been addressed. Therefore, the present study aims to determine the impressive factors in executive function during pregnancy. MATERIALS AND
methodsThis study was conducted on pregnant women referred to Imam Hossein and Taleghani Hospital in Tehran between October 2019 and October 2021. Eligible people completed the Brain Executive Function Questionnaire of the adult self-report form at the following three points of follow-up: the first trimester of pregnancy, the third trimester of pregnancy, and postpartum. The executive performance scores of the studied subjects and the influencing factors were reported.
resultsIn this study, 210 pregnant women with a mean age of 28.70 ± 7.08 years filled out the questionnaire three times. The Global Executive Composite (GEC) of the study subjects in the third trimester of pregnancy was significantly higher than in the first trimester of pregnancy and after delivery (a higher score indicates a greater impairment of the brain's executive function), which indicates lower executive function during the third trimester. The GEC of the study subjects after delivery was significantly higher than in the first trimester of pregnancy. The level of education of the subjects was the covariate of the changes in the study subjects' executive performance.
conclusionScore of the postpartum period in comparison to the first trimester was significantly decreased, yet. Also, the changes in the executive function of the brain during pregnancy were influenced by the level of education, including better function and lower decline in the high-educated group.
