1 · What the graph read from it

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.

2 · The registry

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

backgroundWhether diagnostic oral glucose tolerance test (OGTT) values are associated with neonatal hypoglycemia (NH) in women with diet-controlled gestational diabetes mellitus (GDM) remains uncertain. We aimed to evaluate the associations of diagnostic OGTT values with neonatal glycemic outcomes and to identify other determinants of NH in this population.

methodsIn this retrospective cohort study, 2,051 singleton pregnancies with diet-controlled GDM were included from a maternal and child health center in Liaocheng, China, between January 2019 and August 2023. Diagnostic fasting blood glucose (FBG), 1-hour post-glucose (1hPG), and 2-hour post-glucose (2hPG) values from the 75-g OGTT were analyzed. Restricted cubic spline (RCS)-based linear and logistic regression models were used to assess possible non-linear associations with neonatal 1-h postnatal blood glucose and NH after adjustments.

resultsNH occurred in 12.0% of neonates (247/2,051). After multivariable adjustment, neither standard regression nor RCS analyses showed significant overall or non-linear associations between diagnostic OGTT values and NH or neonatal 1-h postnatal blood glucose (all P > 0.05). Gestational age at delivery was independently protective, with each additional week associated with a lower risk of NH (aOR = 0.62, 95% CI 0.48-0.80). Cesarean delivery was associated with higher odds of NH than vaginal delivery (aOR = 2.24, 95% CI 1.62-3.10).

conclusionsIn diet-controlled GDM pregnancies, diagnostic OGTT values were not independently associated with NH or neonatal 1-h postnatal blood glucose. These findings suggest that subsequent clinical management and obstetric factors, particularly gestational age at delivery and delivery mode, may be more important than the diagnostic OGTT value itself for neonatal glycemic outcomes.
