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

Pregnancy can be seen as a positive time for women migraineurs because the elevated estrogen and endogenous opioid levels raise the pain threshold and the stable hormone levels, which no longer fluctuate, eliminate a major trigger factor for the attacks. In a great majority of cases, indeed, migraine symptoms spontaneously improve throughout pregnancy. Generally, migraine without aura (MO) improves better than migraine with aura (MA), which can occur ex novo in pregnancy more frequently than MO. After childbirth, the recurrence rate of migraine attacks increases, especially during the first month; breastfeeding exerts a protective effect against the reappearance of attacks. Migraine and pregnancy share a condition of hypercoagulability; therefore, attention must be paid to the risk of cardiovascular disorders, like venous thromboembolism and ischemic or hemorrhagic strokes. Some of these diseases can be linked to preeclampsia (PE), a serious complication of pregnancy, characterized by hypertension, proteinuria, or other findings of organ failure. This condition is more common in migraineurs compared with non-migraineurs; furthermore, women whose migraines worsen during pregnancy had a 13-fold higher risk of hypertensive disorders than those in which migraine remitted or improved. Pregnancy is generally recognized to exert a beneficial effect on migraine; nonetheless, clinicians should be on the alert for possible cardiovascular complications that appear to be more frequent in this patient population.
