Maternal antibiotic exposure disrupts microbiota and exacerbates hyperoxia-induced lung injury in neonatal mice.
Article in Pediatric research, 2021. 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
backgroundPerinatal antibiotic treatment alters intestinal microbiota and augments hyperoxia-induced lung injury in mice offspring. The effect of maternal antibiotic treatment (MAT) during pregnancy on the lung microbiota and its relationship with lung injury remains unknown.
methodsWe fed timed-pregnant C57BL/6N mice sterile drinking water containing antibiotics from gestational day 15 to delivery. Neonatal mice were reared in either room air (RA) or hyperoxia (85% O
resultsMAT during pregnancy significantly reduced the total number of commensal bacteria in the intestine and birth body weight of newborn mice compared with control newborn mice. Neonatal hyperoxia exposure impaired alveolarization and angiogenesis, which was exacerbated by MAT. Neonatal hyperoxia altered the composition and diversity of intestinal and lung microbiota and MAT further exacerbated neonatal hyperoxia-induced intestinal and lung dysbiosis.
conclusionsMAT during pregnancy exacerbates hyperoxia-induced lung injury probably through the modulation of intestinal and lung microbiota in neonatal mice. IMPACT: MAT during pregnancy reduced the total number of commensal bacteria in the intestine. Neonatal hyperoxia altered the composition and diversity of intestinal and lung microbiota. MAT exacerbated neonatal hyperoxia-induced intestinal and lung dysbiosis. Neonatal hyperoxia exposure impaired alveolarization and angiogenesis, which was exacerbated by MAT. Avoiding and carefully using antibiotics during pregnancy is a potential therapeutic target for preventing lung injury in hyperoxia-exposed infants.
