Cerebral Venous Sinus Thrombosis Following Varicella Infection: A Case Report.

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.
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
A 38-year-old man presented to the emergency department with a severe frontal headache, which began three days prior without visual, speech, or balance disturbances. His past medical history was unremarkable, apart from raised cholesterol. He confirmed a recent primary Varicella-zoster virus infection (chicken pox) two weeks prior. Clinical examination revealed crusted varicella lesions on the arms, trunk, and thighs. The neurological examination revealed no deficits, neck rigidity, or abnormal gait. Routine blood investigations were unremarkable. Autoantibody screen and HIV serology were negative. CT head non-contrast showed evidence of hyperdense bilateral transverse sinus thrombosis. To confirm the findings, a CT venogram showed extensive and occlusive left transverse and sigmoid sinus thrombosis with further extension into the left internal jugular vein. The stroke team advised an MRI of the head, which reported no acute infarction, and magnetic resonance venography (MRV), which further confirmed the occlusion in the left transverse sinus, sigmoid sinus, and jugular vein. Hematology was involved and advised to start warfarin and bridging therapy with enoxaparin. His migraines experienced a substantial improvement within 48 hours of commencing treatment. He was subsequently discharged with outpatient follow-up. He continued on warfarin with a therapeutic international normalized ratio (INR) range of two to three for one year. A thrombophilia screen,
