Associations between epileptic seizures in pregnancy and adverse pregnancy outcomes: A systematic review and meta-analysis.
Synthesis in PLoS medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundEpileptic seizures during pregnancy may increase the risk of adverse pregnancy outcomes. Socioeconomic disparities in epilepsy incidence may extend to seizure control. We conducted a systematic review and meta-analysis to assess the association between epileptic seizures during pregnancy and adverse pregnancy outcomes. We also evaluated the association between socioeconomic and individual-level factors and seizure occurrence. METHODS AND
findingsWe searched MEDLINE, Embase, CINAHL, and PsycINFO databases from inception to May 2025 for observational studies on pregnant women with epileptic seizures. We compared maternal and foetal outcomes in pregnant women with and without seizures and assessed the association between seizure occurrence and socioeconomic or individual-level factors. We used the Newcastle-Ottawa Scale to assess the risk of bias of included studies. Meta-analyses using random effects model were performed to estimate pooled odds ratios (ORs) with 95% confidence intervals (CIs). From 13,381 identified publications, 25 studies (24,596 pregnancies) are included in this analysis. In pregnant women with epilepsy, women with seizures compared to those without had increased odds of caesarean birth (OR 1.62, 95% CI 1.14 to 2.30, p = 0.007), peripartum depression (OR 2.20, 95% CI 1.04 to 4.65, p = 0.04), and small for gestational age baby (OR 1.32, 95% CI 1.03 to 1.69, p = 0.03). The odds of preterm birth (OR 1.66, 95% CI 1.29 to 2.15, p < 0.001), low birthweight (OR 1.47, 95% CI 1.12 to 1.93, p = 0.006), and small for gestational age baby (OR 1.44, 95% CI 1.19 to 1.74, p < 0.001) were higher in women with seizures compared to women without epilepsy. The risk of seizures was greater in pregnant women with epilepsy with low income compared to those with higher income (OR 1.57, 95% CI 1.22 to 2.02, p < 0.001), and in women with focal epilepsy compared to those with generalised epilepsy (OR 1.84, 95% CI 1.54 to 2.20, p < 0.001). The number of studies for some outcomes was small, limiting subgroup analyses and detection of heterogeneity.
conclusionEpileptic seizures are associated with increased risks of adverse maternal and foetal outcomes. Risk assessment to identify women with epilepsy at highest risk of seizures is needed to optimise care.
