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

backgroundThere is interest in whether supplements, including vitamin D and marine omega-3 (n-3) fatty acids, may be effective migraine prophylaxis. However, few studies have evaluated whether vitamin D or n-3 fatty acid supplementation may reduce migraine frequency or severity.

methodsParticipants in the VITamin D and OmegA-3 TriaL (VITAL) were assigned to vitamin D

resultsAmong the 25,871 participants in VITAL, 1032 participants had a history of probable migraine and provided information on changes in migraine frequency and severity. The percentage of individuals reporting decreases in migraine frequency did not differ between active (69.0%) and placebo vitamin D (68.4%) (P value = 0.54) or between active (67.8%) and placebo n-3 fatty acid (69.6%) (P value = 0.82). Similarly, the percentage of individuals reporting decreases in migraine severity did not differ between active (64.1%) and placebo vitamin D (65.0%) (P value = 0.86) or between active (64.5%) and placebo n-3 fatty acid (64.5%) (P value = 0.96).

conclusionsNeither vitamin D nor marine n-3 fatty acid supplementation, compared to placebo, affected migraine frequency or severity among middle-aged or older adults.
