Factors Associated With Perceived Cognitive Dysfunction in Patients With Primary Brain Tumors: The Utility of the Neuro-QoL Cognition Function Scale.
Observational study in Cancer medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02851706 (Evaluation of the Natural History of and Specimen Banking for Patients With Tumors of the Central Nervous System), which is not on this map.

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.

Abstract
backgroundPrimary brain tumor (PBT) patients commonly experience cognitive dysfunction. This study aims to describe the prevalence and factors associated with perceived cognitive function (PCF) in PBT patients enrolled in a natural history study (NCT02851706: Principal Investigator T. S. Armstrong).
methodsThe Neuro-QoL Cognition Function was used to measure PCF with T-scores < 40 categorized as cognitively impaired. Clinical and demographic characteristics, patient-reported outcomes (PROs: symptom burden, depression, anxiety), and KPS were collected and characterized using descriptive statistics. Univariate tests on PCF with p-value < 0.10 were performed and included in a subsequent multivariate logistic regression with backward selection. Clinical variables and PROs were evaluated separately, then combined for a final multivariate model with p-value < 0.05.
resultsThe cohort included 327 patients (median age: 47 years [range: 18-85], primarily white [78%] males [55%] with high-grade tumors [73%]). Perceived cognitive impairment occurred in 29% of patients. Patients presenting with cognitive dysfunction at diagnosis, or who had undergone multiple surgeries, were more likely to have poor PCF, as were those currently on corticosteroids and reporting cognitive symptoms and symptom interference. Evaluated together, a multivariate model found that only higher scores on symptom interference and the cognitive symptom factor increased the likelihood of cognitive impairment (symptom interference odds ratio [OR] = 1.25, 95% confidence interval [CI] [1.09, 1.44], p < 0.001; cognitive symptom factor OR = 1.81, 95% CI [1.50, 2.19], p < 0.001) with an 84% classification rate.
conclusionsSelf-reported cognitive symptoms and interference were the strongest patient-reported correlates of PCF and should be interpreted as concurrent associations among related constructs. Further psychometric and longitudinal work is needed to clarify the incremental clinical value of the Neuro-QoL Cognition Function Short Form in PBT care and research.
