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

purpose of reviewIt was reported that migraine was associated with increased vascular risks, and the association between high blood pressure (BP) and migraine was believed by some to be the missing link. The current review focused on the associations between migraine and hypertension and BP per se, and evidence on the directionality of the associations was also reviewed. RECENT

findingsIn cross-sectional studies, the findings regarding whether migraine was associated with hypertension were inconsistent, and positive, neutral, or even inverse associations were reported. When individual BP parameters were examined separately, migraine was associated with higher diastolic BPs, and perhaps lower pulse pressures, although the associations with systolic BPs were incongruent. When studies mainly recruiting elderly patients are excluded, it appeared that studies reporting a positive association between migraine and high BPs, particularly high diastolic BPs, outnumbered those with an inverse or neutral association. In longitudinal studies, there was evidence that migraine patients were at increased risks of developing hypertension at follow-up. However, studies examining whether high BP could predict new-onset migraine yielded conflicting results. The association between migraine and hypertension is still a controversial issue, and a firm conclusion is precluded by the heterogeneities in methodologies and study populations. Migraine patients are at increased risk of developing hypertension. However, whether hypertension predicts migraine remains inconclusive. Further studies are needed to clarify the complicated association between BP and migraine.
