Clinical and prognostic characteristics of cerebral venous thrombosis at high altitude: a single-center retrospective study of Tibet.
Article in Journal of neurology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveData regarding diagnosis, management, and prognosis of patients with cerebral venous thrombosis (CVT) from high altitude are limited. The aim of the present study is to identify the clinical features, risk factors, and outcomes of cerebral venous thrombosis (CVT) in Tibet.
methodsWe retrospectively included patients with a diagnosis of CVT consecutively admitted to Tibet Autonomous Region People's Hospital between July 2015, and September 2022. The risk factors, clinical and radiological presentations, treatment and outcomes were analyzed.
resultsA total of 38 patients with CVT were included in this study. The median age was 31 years, and females accounted for 63.2%. Patients of Tibetan nationality accounted for 71.1% (n = 27) and the median altitude of residence in Tibet was 3800 m (3657, 4054). Headache was the most common symptom (92.1%). The most common risk factors of CVT were infection in the past 4 weeks (34.2%) and pregnancy or puerperium (23.7%). Lateral sinus (transverse and/or sigmoid sinus) (68.4%) and superior sagittal sinus (55.3%) were the most commonly involved. The D-dimer increased in 31 patients (81.6%). All three patients who died in hospital and during follow-up had risk factor of recent infection. Favorable outcome at follow-up with a median length of 454 days (189, 1059) was observed in 85.3% of patients.
conclusionsCVT at high altitude is more common in young patients and women, with various clinical manifestations and risk factors. Recent infection is the most common risk factor and may increase the mortality of CVT at high altitude. The long-term prognosis of CVT at high altitude is favorable.
