A Multicenter Retrospective Cohort Study of Pregnancy Outcomes in Idiopathic Oligohydramnios at Term.

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
Objective: The effect of idiopathic oligohydramnios or isolated oligohydramnios on perinatal outcomes at term pregnancies is understudied. This study aimed to show the current epidemiological status of idiopathic oligohydramnios in mainland China, evaluate the pregnancy outcomes, and discuss the optimal delivery opportunity and mode. Methods: We conducted a retrospective cohort study of 106,225 term pregnancies from 37 hospitals in mainland China. All cases that delivered a non-anomalous singleton fetus between 37 Results: The incidence of idiopathic oligohydramnios in singleton pregnancies at term was 2.6%. Compared with control pregnancies, the idiopathic oligohydramnios group was characterized by lower birth weights and higher cesarean section rates (P <0.01, respectively). From early-term and full-term to late-term, a pregnancy with idiopathic oligohydramnios exhibited the trend of lower risk of cesarean delivery and neonatal intensive care unit (NICU) admission but a higher risk of meconium-stained amniotic fluid, non-reassuring fetal heart rate status (NRFHRS), and emergency cesarean delivery (P <0.01, respectively). Notably, the rate of Apgar score <7 at 5 min and cesarean section was the lowest when delivery occurred during the 39 Conclusion: The incidence of adverse pregnancy outcomes is higher in the idiopathic oligohydramnios group than in the control group. Adverse outcomes seem lowest in the group of vaginal delivery during the 39
