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

backgroundPeople with migraine may prefer over-the-counter (OTC) drugs because of multiple reasons, but their overuse can cause medication overuse headaches. This analysis of the ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE (OVERCOME [Japan]) 2nd study describes the real-world use of OTC headache drugs and the challenges that potentially prevent people with migraine from accessing appropriate medical management in Japan.

methodsThis analysis of the cross-sectional, population-based, nationwide online survey included adults with migraine. Respondents reported their experiences with prescription and OTC drugs for migraine, migraine-specific drug awareness, and attitude towards migraine. Subgroup analyses were performed based on the number of monthly headache days (MHD) and the frequency of OTC drug use/month.

resultsThe 19,590 respondents with migraine (68.8% female; mean [SD] age 40.5 [13.1] years) had mean (SD) 3.5 (5.2) MHDs; 29.0% consulted doctors in the past year for migraine. OTC drug use in the past year was common (≥ 62.1%) regardless of doctor consultation or number of MHDs. Among respondents who answered that they would usually use prescribed drugs when they have a migraine attack, 35.2% reported that they would typically use OTC drugs too. The frequency of OTC drug use was the same or higher than that of prescribed drugs in 51.3% of the respondents who consulted doctors in the past year. Only 14.6% of respondents discussed OTC drugs with doctors during consultations in the past year. Migraine-specific drug access and awareness were limited even among frequent OTC drug users (≥ 10 days/month); 18.2% used triptans, but 65.5% never heard of it. Among 37.1% of respondents who had hesitated to visit a doctor, 'I could handle it myself with OTC medicine' was the most common reason for hesitation (34.9%).

conclusionOTC drug use is common among people with migraine; however, it is not frequently discussed with doctors. Many respondents, even those with frequent OTC drug use, did not have access or awareness of migraine-specific drugs. To prevent medication overuse for migraine, the use of OTC drugs should also be discussed and managed.
