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

backgroundSome angiotensin converting enzyme (ACE) inhibitors have previously been shown to be effective in migraine prophylaxis. The aim of this study was to evaluate whether Enalapril is effective in migraine prophylaxis.

methodsIn this randomized, double-blind, placebo-controlled clinical trial, the effects of 10 mg Enalapril given daily were compared with those of matched placebo in 40 migraineurs for 2 months. Response to treatment was assessed at 0, 1, and 2 months after the start of intervention according to headache parameters like frequency, severity, and duration. This trial is registered with Iranian Registry of Clinical Trials (IRCT), number IRCT138711011570N1.

resultsA significant effect on reducing migraine attack more than 50% at first and second months (P=0.016) occurred in Enalapril group. Indeed, at the first and second months of treatment, the severities (P=0.000 and P=0.000) and duration (P=0.037 and 0.003) in the Enalapril treated group were significantly lower than in the placebo group.

conclusionEnalapril may be effective in migraine prophylaxis according to its effect in decreasing the frequency, severity, and duration of headaches. The results support the previous suggestions on usage of ACE inhibitors in migraine prophylaxis.
