Epidemiology and survival of primary intracranial malignant tumor patients with drop metastasis: a population-based 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
backgroundDrop metastasis significantly impacts the survival of patients with primary intracranial malignant tumors. Using the information of collaborative stage from the SEER database, we aim to analyze the epidemiology and prognosis of primary intracranial malignant tumor patients with drop metastasis.
methodsWe analyzed the distribution of patients and the frequency according to the demography and clinical characteristics of patients with drop metastasis. We also analyzed the survival of these patients with drop metastasis. Multivariate Cox proportional hazards models were used to analyze possible prognostic indicators.
resultsA total of 56,839 cases with primary intracranial malignant tumors were ultimately included in this cohort study. A total of 792 cases were confirmed to have drop metastasis. The average rate of drop metastasis was 1.4%. Most of the patients with drop metastases were diagnosed before ten years old. The three most common primary intracranial malignant tumors with drop metastasis were glioblastoma, embryonal/primitive/medulloblastoma, and anaplastic astrocytoma. Embryonal/primitive/medulloblastoma had the highest drop metastasis rate, at 11.6%. Tumors located in the infratentorial space and ventricles had a higher rate of drop metastasis than tumors in other locations. The prognosis for patients with drop metastasis is poor. Routine complete treatment (surgery of the primary tumor plus chemoradiotherapy) can significantly improve overall survival.
conclusionWe conducted a population-based analysis of primary intracranial malignant tumor patients with drop metastasis. Our study can help clinicians acquire general information on the epidemiology and survival of primary intracranial malignant tumor patients with drop metastasis.
