Association of bipolar disorder and schizophrenia in women with risk of gestational diabetes: a systematic review and meta-analysis.
Synthesis in BMC pregnancy and childbirth, 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
backgroundPsychiatric disorders are severe mental illnesses associated with insulin resistance, systemic inflammation, and neurohormonal dysfunction. To synthesize the available evidence and provide recommendations for the clinical management of this patient population, this study aimed to comprehensively examine and meta-analyze the association between bipolar disorder, schizophrenia, and the risk of gestational diabetes mellitus (GDM).
methodA systematic search was conducted in PubMed, Embase, Scopus, Web of Science, and Google Scholar. Studies reporting an association between pre-pregnancy bipolar disorder or schizophrenia and GDM were included. Random-effects models were used for meta-analysis, and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated.
resultsAmong 10 eligible studies, the meta-analysis revealed that women with bipolar disorder (RR: 1.59; 95% CI: 1.13-2.23) and schizophrenia (RR: 2.07; 95% CI: 1.39-3.07) had a significantly higher risk of developing GDM. Evidence regarding this association after controlling for confounding factors was limited. however, pooled analysis of the few available studies showed RRs of 1.43 (95% CI: 0.83-2.38) for bipolar disorder and 1.29 (95% CI: 1.07-1.55) for schizophrenia.
conclusionsThis study provides evidence that bipolar disorder and schizophrenia are associated with an increased risk of gestational diabetes. Regular screening and management of modifiable risk factors, alongside mental health stability, are essential in women of reproductive age. Future prospective studies should investigate the underlying mechanisms of this association.
