How two-child policy affects cesarean section in women with advanced maternal age (AMA): using the Robson classification system.
Article in BMC pregnancy and childbirth, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesTo study the possible associations between advanced maternal age and cesarean section(CS) under the two child policy.
methodsThis study used a cohort study from Dongguan People's Hospital in Guangdong Province, China from 2017 to 2020. The cohort was restricted to women aged ≥ 20 who give birth to babies with a gestational age of > 28 weeks and a weight of > 1000 g. Divide the advanced maternal age (AMA) pregnant women into two age groups: 35-39 years old and 40 years old or older age. We analyzed CS rate and CS contribution using the modified Robson classification system. Frequency of cesarean was determined for each group and compared by using χ
resultsOverall, 47654 women were included, of which 7924 (16.63%) were between the ages of 35 and 39, and 1529 (3.21%) were aged 40 or older. The total CS rate is 40.64%, with 36.10% for mothers aged 20 to 34, 57.90% for women aged 35 to 40, and 64.75% for women aged 40 or older age. In the AMA groups (n = 9453), Robson group 2' was the most common, followed by groups 5 and 10. Women at 40 years or older age were 3 times more likely to undergo a cesarean delivery in Robson group 1', and 1.76 times more likely in group 10. The CS rate in group 2' were statistically significantly higher in the very AMA group.
conclusionsThe CS rates increased noticeably with maternal age under the two child policy. Based on the modified Robson classification system, AMA women should pay more attention to primiparous women with single pregnancy, uterine scars, and premature birth in multiple pregnancies.
