The effect of maternal age and duration of labor on perinatal and neonatal outcomes: a retrospective cohort study.
Article in Annals of translational medicine, 2022. 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
Background: This study aimed to investigate the effect of maternal age and duration of labor on perinatal and neonatal outcomes. The results of this study are expected to provide a basis to aid maternal and child health care personnel to implement health education for late childbearing women. Methods: This was a retrospective observational study, wherein 9,241 parturients were included from 2016 to 2018. Parturients were divided into three groups based on age: <28 (n=2,911), 28-30 (n=3,631), and >30 (n=2,699) years. According to the total duration of labor, those who did not undergo cesarean section (CS) were subgrouped into <420 minutes (n=4,065) and ≥420 minutes (n=4,094) groups. A multivariate logistic regression model was used to investigate associations between age/total duration of labor group factors to different postpartum outcomes, including a switch to emergency CS, puerperal morbidity, abnormal fetal heart rate, and meconium-stained amniotic fluid (MSAF). Results: The rates of postpartum outcomes significantly differed in maternal age groups, including switch to emergency CS (9.07% Conclusions: With the adjustment of covariates. Higher maternal age seems associated to the risk of switching to emergency CS and having abnormal fetal heart rate; longer total duration of labor seems associated to the risk of puerperal morbidity and MSAF.
