Maternal and neonatal outcomes of Group B Streptococcus colonization: a retrospective study.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundGroup B Streptococcus (GBS) colonization is one of the major causes of severe neonatal infections. The study was intended to identify GBS colonization in pregnant women, explore its potential risk factors, and analyze the impact of GBS on outcomes for both mothers and newborns. MATERIAL AND
methodsA retrospective research was carried out on pregnant women who had undergone GBS screening and delivered from June 2020 to December 2022. Pregnant women between 35 and 37 weeks of gestation had GBS screening using real-time polymerase chain reaction (RT-PCR). The clinical characteristics and outcomes of mothers and newborns were collected. The risk factors linked to maternal GBS colonization and its impact on adverse outcomes for mothers and neonates were assessed using chi-square and logistic regression analyses. The composite neonatal adverse outcomes included low Apgar scores, neonatal pneumonia, neonatal hyperbilirubinemia, neonatal sepsis, or low birth weight.
resultsOverall, the rate of GBS positivity was 10.63% (551/5183), and the rate of maternal GBS screening was 88.4%. Diabetic pregnant women were more likely to become colonized with GBS. Our research revealed that GBS carriers experienced higher rates of fetal distress and neonatal adverse outcomes than non-GBS carriers. Fetal distress (OR, 1.940; 95% CI, 1.355 to 2.778, P < 0.001), neonatal sepsis (OR, 5.063; 95% CI, 2.536-10.109, P < 0.001), low Apgar scores (OR, 2.097; 95% CI, 1.184-3.715, P = 0.011), neonatal pneumonia (OR, 1.638; 95% CI, 1.039 to 2.582, P = 0.034) and neonatal hyperbilirubinemia (OR, 1.438; 95% CI, 1.080 to 1.915, P = 0.013) were significantly related to maternal GBS colonization. When we used the composite adverse neonatal outcomes as the dependent variable and analyzed the influencing factors, the logistic regression analysis revealed that GBS colonization was still significantly related to an elevated risk of adverse neonatal outcomes (OR = 1.752, 95% CI, 1.389-2.208; P < 0.001).
conclusionsDiabetes may be a risk factor for maternal GBS colonization. Moreover, in this study, GBS colonization correlated with neonatal adverse outcomes but not with maternal outcomes.
