The Trend in Delayed Childbearing Age and Its Potential Impact on Adverse Maternal-Perinatal Outcomes in Developed and Developing Countries: A Narrative Review.
Review in Iranian journal of public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Due to the significant advancement of modern societies, higher education, career growth, and economic independence, more young girls are likely to delay childbearing beyond 30 years of age. The trend of delayed childbearing is more pronounced in industrialized countries but is also becoming common in emerging countries. Delayed childbearing has been linked with several adverse maternal-perinatal outcomes, including hypertensive disorders of pregnancy, abnormal placentation, gestational diabetes mellitus, pre-term births, low birthweight, perinatal mortality, congenital birth defects, and chromosomal abnormalities. In this review, we have highlighted the trend of delayed childbearing age, the role of education and employment in delayed childbearing age, and its potential impact on adverse maternal-perinatal outcomes in developed and developing countries.
