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

Objective This study examined the prevalence of migraine in nurses in Japan, which, to our knowledge, has not been documented in English. Methods From April to May 2021, we administered a questionnaire to 229 nurses working at Keio University Hospital to investigate the prevalence and characteristics of headache among nurses in Japan. Headaches were classified as migraine or tension-type headache (TTH) based on the International Classification of Headache Disorders 3rd edition (ICHD-3). Results In total, 80 patients (34.9%) had primary headaches, including 47 (20.5%) with migraine and probable migraine and 33 (14.4%) with TTH and probable TTH. We found a significant difference in the Numerical Rating Scale score, nausea and vomiting, photophobia, phonophobia, and aggravation by routine physical activity between migraine and TTH. The specificities for a migraine diagnosis were 100% and 93.9% for nausea/vomiting and photophobia, respectively. Only 8.8% of patients had their headaches diagnosed by a physician. Conclusion Migraines have a high prevalence (>20%) among nurses and are often under-diagnosed. In many cases, headache-associated symptoms are more important than laterality or other characteristics for the diagnosis. Many nurses are treated for headaches without a correct diagnosis. Further education regarding primary headaches may be necessary for health practitioners as well as society.
