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

objectiveTo investigate whether maternal migraine was associated with preterm birth. STUDY

designCase-control sample within a population-based study of risk factors for cerebral palsy (CP). Infants without CP were matched for gestational age with those with CP. Maternal migraine was self-identified at first prenatal visit, most in the first trimester.

resultInfants without CP born to women with migraine had a higher rate of preterm birth (odds ratio (OR)=3.5, 95% confidence interval (CI) 1.5, 8.5), as did infants who died in the perinatal period (OR=7.3, 95% CI 0.98, 54), the difference marginal for nominal statistical significance. In all outcome groups, infants of women with migraine had a higher observed rate of suboptimal intrauterine growth. In term infants, the rate of maternal migraine was higher in those with CP than in controls (OR=2.18, 95% CI 0.92, 5.25). Pre-eclampsia was reported more frequently in women with migraine who gave birth to a child with CP or a perinatal death, particularly in those born preterm; OR=5.1 (1.3, 20) and OR=2.9 (1.1, 7.6), respectively, but not in women giving birth to a control whether term or preterm.

conclusionMaternal migraine, as self-reported early in pregnancy, was associated with preterm birth in survivors without CP and in infants who died in the perinatal period. The combination of maternal migraine and pre-eclampsia was associated with CP and perinatal death. The association of maternal migraine with outcomes of pregnancy warrants further study.
