One year after gestational diabetes: metabolic changes and predictors of postpartum dysglycaemia.
Review in Acta diabetologica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWomen with previous gestational diabetes mellitus (GDM) are at high risk of developing type 2 diabetes mellitus (T2DM). Although early postpartum screening is recommended, metabolic changes occurring during the first year remain poorly characterized, and Italian guidelines do not include assessment at this time point.
aimTo evaluate glycaemic and metabolic changes one year after delivery in women with previous GDM and identify clinical and lifestyle predictors of postpartum glucose impairment.
methodsA cohort of 134 women with prior GDM was assessed at 6-12 weeks (T0) and one year postpartum (T1). Anthropometric, biochemical, nutritional, lifestyle, and quality-of-life parameters were collected. Dietary habits were evaluated using a 3-day food diary and the PREDIMED questionnaire; physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). Logistic regression models were used to identify predictors of altered OGTT at T1.
resultsAt baseline, 32.9% of women showed altered OGTT; this increased to 38.8% at one year, while T2DM prevalence rose from 2.2 to 5.2%. Insulin therapy during pregnancy was the only independent predictor of dysglycaemia at T1 (OR 3.5, 95% CI 1.28-9.50, p = 0.015). Women with altered OGTT reported lower SF-36 scores in the domains "role limitations due to physical health" (p = 0.016) and "health change" (p = 0.030). Breastfeeding was associated with more favourable glucose outcomes (p = 0.009).
conclusionsOne-year follow-up after GDM reveals early metabolic and psychosocial differences not detectable in the early postpartum period. Insulin therapy during pregnancy strongly predicts glucose impairment, highlighting the need for extended postpartum surveillance and targeted lifestyle interventions.
