1 · What the graph read from it

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.

2 · The registry

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

introductionMigraine is one of the most prevalent conditions worldwide. This systematic review aimed to evaluate the association between migraine, its subtypes, and adverse pregnancy outcomes. MATERIAL AND

methodsEligible cohort and retrospective case-control studies were included from PubMed and Embase databases from their inception to May 2024. Adverse pregnancy outcomes of interest were preeclampsia, preterm birth, low birthweight, small for gestational age, and placental abruption. Study quality was assessed using the Newcastle-Ottawa Scale. Meta-analyses of the outcomes with their odds ratios (ORs) and adjusted ORs (aOR), including a 95% confidence interval (CI), were performed using RevMan. Outcomes were pooled using random effects models, with separate analyses for cohort and retrospective case-control studies. The protocol was registered with PROSPERO (no. CRD42023404759).

resultsThis meta-analysis included 19 studies (11 cohort and 8 retrospective case-control) encompassing 1 420 690 deliveries. Significant associations were observed between migraine and increased risk of preeclampsia (cohort: aOR 1.28 [95% CI: 1.11-1.47], I

conclusionsPregnant women with migraines have a higher risk of preeclampsia and preterm birth compared with those without migraines. Migraine could be associated with an increased risk of low birth weight and small for gestational age. Sub-analyses indicate an elevated risk of preeclampsia and preterm birth across migraine subtypes. Notably, no previous meta-analyses have differentiated between migraine subtypes. Additional studies are needed to strengthen these findings.
