Effect of maternal age on neonatal outcomes in very low birth weight singleton infants: a population-based study.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLittle is known on the impact of maternal age (MA) on very low birth weight (VLBW) infants' outcomes. We tested the hypothesis that at both ends of MA there are increased adverse neonatal outcomes in VLBW infants.
methodsWe used the Israel National Neonatal Network VLBW (≤1500 g) database. Maternal age was stratified as: <20, 20-24, 25-34 (reference group), 35-39 and ≥40 years. Statistical analyses were univariate and multivariable logistic regression analysis.
resultsAfter adjustment, the infant outcomes of older mothers were similar to those of the reference group for mortality, RDS, severe ROP, NEC and sepsis. Mothers < 20 and 20-24 years old had higher odds of IVH grades 3-4 (OR 1.45, 95% CI 1.09-1.93 and OR 1.26, 95% CI 1.10-1.45, respectively), and BPD (OR 1.55, 95% CI 1.13-2.13 and OR 1.40, 95% CI 1.22-1.62, respectively). There were higher odds for PVL in infants of <20 year-old mothers (OR 1.83, 95% CI 1.26-2.65) and in infants of 35-39 year-old mothers (OR 1.38, 95% CI 1.12-1.69). Poor composite outcomes were significantly higher in the youngest maternal age categories (<20-year-old mothers (OR 1.63, 95% CI 1.28-2.08), and 20-24-year-old (OR 1.28, 95% CI 1.15-1.43).
conclusionsNeonatal outcomes differ in relation to maternal age among very low birth weight newborns, with adverse outcomes more predominant in infants of younger mothers.
