Survival differences in malignant meningiomas: a latent class analysis using SEER data.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSeveral studies have used demographic characteristics to examine differences in survival time for patients with malignant meningioma (MM). Latent class analysis (LCA), with its ability to identify mutually patterns of patients in a heterogeneous population. The aim of our study was to analyze the heterogeneity of sociodemographic characteristics in meningioma.
methodsThe data of patients diagnosed with malignant meningioma (n = 1,562, age > 18 years old) were extracted from the Surveillance, Epidemiology, and End Result database. Data on sociodemographic characteristics such as age, sex, race, NHIA, marital status, household income, rural or urban residential area, and overall survival time were included. LCA was used to identify heterogeneous patterns of MM. each group was explored using Bayesian network analysis.
resultsIn total, 1562 patients with MM were processed by the LCA model; the 4-class latent class models were the best fit. LCA identified four survival groups: highest, intermediate-high, low-to-moderate, and lowest survival groups. Patients with the longest survival times-93.59 months-were 40-59 years old, female, Black, non-Hispanic, married, and had a family income of $60,000-$74,999 and lived in densely populated areas. Bayesian networks revealed correlations between patients with MM and sociodemographic characteristics in different latent class groups.
conclusionWe identified and verified differences in clinical and sociodemographic characteristics between survival groups. A comprehensive understanding of the "people-oriented" subgroup characteristics will greatly benefit the diagnosis and treatment of MM.
