Key prognostic risk factors linked to poor functional outcomes in cerebral venous sinus thrombosis: a systematic review and meta-analysis.

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
backgroundCerebral venous sinus thrombosis is a rare stroke with several clinical manifestations. Several studies have identified prognostic risk factors associated with poor functional outcomes and established predictive models. This systematic review and meta-analysis assessed the overall effect size of all prognostic risk factors.
methodsA systematic review was conducted to explore all prognostic risk factors in studies published from the initial to June 2024 among 5 Databases included PubMed / Medline, Scopus, EBSCOhost, Web of Science, and Cochran Library. The quality of the methodology was analyzed using the Newcastle-Ottawa Scale. Data analysis was performed using the Statistical Package for Social Sciences (SPSS) version 29.
resultsSixty-four studies involving 18,958 participants with a mean age of 38.46 years and females 63.03% were included in the quantitative meta-analysis. Functional outcomes were primarily measured using the Modified Rankin Scale (mRS), with scores ≥ 2 or ≥ 3 indicating poor outcomes in 35.00% and 60.00% of studies, respectively. For general information, age (InOR = 0.98, 95% CI 0.53-1.43), intracranial hemorrhage (OR = 3.79, 95% CI 2.77-5.20), and ischemic infarction (OR = 3.18, 95% CI 2.40-4.23) were associated with poor functional outcomes. For general and neurological symptoms, headache (OR = 0.22, 95% CI 0.17-0.29), seizure (OR = 2.74, 95% CI 1.76-4.27), focal deficit (OR = 4.72, 95% CI 3.86-5.78), coma (OR = 11.60, 95% CI 6.12-21.98), and consciousness alteration (OR = 7.07, 95% CI 4.15-12.04) were outstanding factors. The blood biomarkers of NLR (log OR = 1.72, 95% CI 0.96-2.47), lymphocytes (Cohen's d = -0.63, 95 CI -0.78--0.47), and D-dimer (lnOR = 1.34, 95% CI 0.87-1.80) were the three most frequently reported factors. Parenchymal lesion (OR = 4.71, 95% CI 1.12-19.84) and deep cerebral venous thrombosis (OR = 6.30, 95% CI 2.92-13.63) in radiological images were two frequently reported factors. CVST patients with cancer (OR = 3.87, 95% CI 2.95-5.07) or high blood glucose levels (OR = 3.52, 95% CI 1.61-7.68) were associated with poor functional outcomes. In the meta-regression analysis, ischemic infarction (P = 0.032), consciousness alteration (P < 0.001), and NLR (P = 0.015) were associated with mRS prediction.
conclusionsPooled effect sizes revealed that ischemic infarction, headache, neurological focal deficit, lymphopenia, and cancer were significantly associated with poor functional outcomes, with low to moderate heterogeneity. Consciousness alterations/deterioration and deep cerebral venous thrombosis were also significant prognostic factors, albeit with substantial heterogeneity. The meta-regression analysis showed that the effect sizes of consciousness alterations/deterioration and NLR increased with worsening mRS scores. Other notable risk factors included age, intracranial hemorrhage, seizures, coma, D-dimer, parenchymal lesions, and hyperglycemia. This systematic review provides a comprehensive overview of the prognostic risk factors for poor functional outcomes in patients undergoing CVST, which can guide clinical decision-making and future research.
