Evaluation of the management of high-risk obstetric patients living with epilepsy: A retrospective study from KwaZulu-Natal, South Africa.
Article in South African family practice : official journal of the South African Academy of Family Practice/Primary Care, 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
backgroundEpilepsy affects approximately 60 million individuals worldwide, with women comprising nearly 50% of the cases. Physiological changes during pregnancy can alter anti-epileptic drug (AED) pharmacokinetics and seizure thresholds, necessitating close therapeutic drug monitoring (TDM). Uncontrolled maternal seizures increase the risk of maternal morbidity, foetal hypoxia and miscarriage. Several AEDs have a known teratogenic potential, highlighting the importance of adherence to clinical guidelines to optimise maternal and foetal outcomes.
methodsA retrospective quantitative study was conducted at a high-risk obstetrics clinic in a public tertiary hospital in KwaZulu-Natal, South Africa, using clinical records from a 5-year period. Of 131 cases, N = 90 met the inclusion criteria. Data were extracted into Microsoft Excel® and analysed using SPSS® (v29). Descriptive and inferential analyses (chi-square, Fisher's exact, Spearman's correlation, Mann-Whitney U and logistic regression) were used to assess the associations between variables.
resultsSodium valproate was prescribed to 60% of patients in the cohort. Folic acid supplementation was documented in 70% of cases (n = 63). Sodium valproate use was significantly associated with polytherapy (p = 0.007). Therapeutic drug monitoring was performed in 56.7% of patients and prenatal ultrasounds in 67.8%. A strong correlation was observed between the total admission frequency and seizure-related admissions (Spearman's ρ = 0.74, p 0.001).
conclusionThe study identified gaps in care, including suboptimal AED selection, limited TDM, inconsistent ultrasound use, frequent polytherapy and increased admissions from poor seizure control. Addressing these may improve the safety and effectiveness of epilepsy management in pregnancy.Contribution: This study contributes novel, context-specific evidence on real-world epilepsy management during pregnancy. It identifies critical gaps in clinical practice, AED selection and therapeutic monitoring.
