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

introductionTension-type headaches (TTH) are prevalent primary headache disorders, affecting approximately 42% of the global population. Characterized by mild to moderate bilateral head pain, TTHs lack symptoms like photophobia and nausea (unless sometimes chronic TTH), distinguishing them from other headaches. They impose significant personal and societal burdens, particularly in high-income countries. Pathophysiology involves genetic factors, myofascial processes, and central sensitization. Gender disparities in healthcare further complicate diagnosis and treatment, often leading to misdiagnosis in women. CASE PRESENTATION: A 56-year-old Middle Eastern woman presented with a 10-month history of moderate occipital headaches, exacerbated by pressure. Initial misdiagnoses attributed her symptoms to psychological factors due to the patient's gender, leading to inadequate treatment. A comprehensive neurological examination was conducted, revealing no neurological deficits but identifying two tender cysts on her scalp. Imaging studies confirmed subdermal and extracranial masses, diagnosed histologically as trichilemmal cysts. These findings suggested a potential link between the cysts and her headache symptoms.

conclusionWhile trichilemmal cysts are typically benign and asymptomatic, their presence on the scalp may contribute to bilateral discomfort with pain localized closer toward her trichilemmal cysts, exacerbating headache symptoms. This case highlights the importance of thorough physical examinations and consideration of atypical headache causes.
