Maternal and Fetal Outcomes in Idiopathic Oligohydramnios vs. Normal Amniotic Fluid Index After 34 Weeks: A Case-Control Study in Eastern India.

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: Oligohydramnios, traditionally associated with adverse perinatal outcomes, often prompt early delivery via caesarean section, even in otherwise uncomplicated pregnancies. However, emerging research suggests that isolated oligohydramnios may not significantly impact neonatal outcomes, warranting re-evaluation of current management strategies. This study aimed to assess maternal and fetal outcomes in patients with idiopathic oligohydramnios diagnosed between 34-40 weeks of gestation, compared to low-risk pregnancies with normal amniotic fluid volume. Methodology: A prospective case-control study was conducted in a tertiary care hospital in Eastern India over a period of one year. The study enrolled 100 pregnant women divided into cases: women with idiopathic oligohydramnios (amniotic fluid index [AFI] ≤5 without any identifiable maternal, fetal, or placental cause) and controls: gestational age-matched women with normal AFI (5-25 cm). Maternal characteristics, labor course, mode of delivery, and neonatal outcomes were analyzed. Statistical analysis was performed using SPSS, with p<0.05 considered significant. Results: The rate of labor induction was significantly higher in cases compared to controls (50% vs. 20%, p=0.001). Meconium-stained liquor (44%) and non-reactive cardiotocography (NRCTG) (60%) were more common in the oligohydramnios group. Caesarean section rates were markedly higher among cases (78% vs. 32%, p<0.001), primarily due to fetal distress (71.8%). Newborns of cases had a higher incidence of small-for-gestational-age (SGA) status (56%). APGAR scores <7 at 1 and 5 minutes were more frequent in cases, with significantly higher neonatal intensive care unit (NICU) admissions (60% vs. 16%, p<0.001). Conclusion: Isolated oligohydramnios is associated with increased obstetric interventions, higher caesarean rates, and adverse neonatal outcomes, including SGA and higher NICU admissions, despite reassuring antenatal fetal surveillance. These findings suggest the need for individualized care and close fetal monitoring rather than automatic early delivery in isolated oligohydramnios cases.
