Estimating the Prevalence of Prescribed Medication Use in Pregnancy with a Systematic Review and Meta-analysis.
Synthesis in Drug safety, 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
introductionMedication use in pregnancy is common, but decisions balancing the needs of maternal and fetal health can be complex. Ongoing monitoring of medication use in pregnancy is essential to ensure their continued safe and appropriate use in this population.
objectiveThe aim of this review is to estimate the prevalence of prescribed medication use in pregnancy.
methodsThis review was carried out in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol was registered in the PROSPERO database (CRD42024533866). PubMed, Medline, Cinahl (EBSCO), APA PsychINFO (EBSCO), Embase (Ovid), Scopus, and Web of Science databases were systematically searched for relevant articles published from January 2010 to May 2025. Inclusion criteria specified that studies provided a value for prescribed medication use in the general population of pregnant women during part or all of the gestational period. Articles were independently dual screened, and relevant data were extracted and validated from included studies. Quality and bias of the studies were assessed using the Joanna Briggs Institute critical appraisal tool for prevalence studies. A narrative synthesis was conducted for all studies. A random-effects meta-analysis with logit transformation was used to pool prevalence estimates (95% confidence interval, CI) where sufficient studies defined medication use in a similar way. Cochran's Q, I
resultsA total of 13,416 unique articles were identified and screened. Seventy studies were included. The pooled prevalence for prescribed medication alone during pregnancy was 56% (CI 44-67%, p < 0.01, I
conclusionsFrom this review, it was evident that a large proportion of women use prescribed medications during pregnancy, but estimates vary greatly. A more standardized approach to studying medication use in pregnancy is needed to allow for consistent and standardised estimates that are comparable across populations.
