Adult primitive neuroectodermal tumors: the prognostic value of supratentorial location.
Article in Journal of neuro-oncology, 2013. 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
Primitive neuroectodermal tumors (PNETs) are tumors which primarily consist of undifferentiated round neuroepithelial cells. Central nervous system PNETs can be divided into two genetically distinct groups: infratentorial PNET (iPNET)/medulloblastoma and supratentorial PNET (sPNET). Currently, the comparative outcome of adult patients with sPNETs and iPNETs is unknown. In this study we have utilized the Surveillance, Epidemiology, and End Results database to perform a comparative analysis of 103 cases of adult sPNET and 669 adult medulloblastoma cases. Additionally we have analyzed various factors to identify their prognostic significance and characterize the optimal treatment for these tumors. Patients with sPNETs were seen to have a significantly worse survival than those diagnosed with medulloblastomas (16 vs. 155 months, p < 0.0001). Elderly patients (15 vs. 114 months, p < 0.0001) and those over the age of 40 (68 vs. 147 months, p < 0.0001) experienced significantly worse survival than younger patients. In contrast, radiotherapy (143 vs. 26 months, p < 0.0001), surgical resection (116 vs. 22 months, p = 0.0010) and the extent of resection (EOR) (173 vs. 81 months, p = 0.0005) resulted in significantly improved patient survival. Multivariate analysis revealed age greater than 40 years (HR: 1.57; 95 % CI: 1.17-2.11; p = 0.0028) and sPNET pathology (HR: 3.41; 95 % CI: 2.47-4.72; p < 0.0001) to be poor prognostic factors for survival while radiotherapy (HR: 0.52; 95 % CI: 0.38-0.71; p < 0.0001) and the EOR (HR: 0.73; 95 % CI: 0.55-0.96; p = 0.023) were associated with significantly improved survival. The treatment of sPNETs should therefore include maximal surgical resection when feasible followed by radiotherapy as these treatments have been demonstrated to confer a survival benefit. Additional studies are needed to identify effective chemotherapeutics and specific treatment regimens for adults with sPNETs.
