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

aimTo determine the precise relationship between the timing of gestational diabetes mellitus (GDM) diagnosis and adverse maternal, perinatal and neonatal outcomes. MATERIALS AND

methodsPubMed, EMBASE, Cochrane Central, Web of Science and CINAHL from inception to March 5, 2026 were systematically searched for observational studies and post hoc analyses or subanalyses of randomised controlled trials comparing outcomes between early-onset GDM (eGDM) and late-onset GDM (LGDM). The tested outcomes included insulin initiation, caesarean delivery, preterm birth, large-for-gestational-age (LGA) infants and neonatal intensive care unit (NICU) admission. Pooled odds ratios (ORs) were calculated using random-effects models. Heterogeneity was assessed using Cochran's Q test and I

resultsThirty-five studies encompassing 105 123 pregnancies met inclusion criteria. eGDM is associated with significantly elevated odds of insulin initiation (OR, 95% CI: 2.26, 1.75-2.91), caesarean delivery (1.16, 1.01-1.33), preterm birth (1.32, 1.05-1.64), LGA (1.29, 1.06-1.58) and NICU admission (1.24, 1.03-1.50). Heterogeneity is substantial (I

conclusionseGDM versus LGDM is associated with higher risks of adverse outcomes, particularly insulin initiation. Gestational age at diagnosis may serve as a key risk stratifier, highlighting the need for risk-stratified approaches rather than universal early surveillance. Future research should prioritise individual-participant data meta-analyses and randomised trials of tailored protocols.
