Article in Der Nervenarzt, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
background and purposeSkull base metastases are a severe complication of various malignant tumors. If cranial nerves are involved even small lesions can cause significant symptoms. Specific clinical characteristics like neurological symptoms, associated primary tumors, prognosis and optimal treatment are poorly defined and are systematically described in this article.
methodsIn a monocentric retrospective study patients with skull base metastases and cranial nerve deficits who received treatment between 2006 and 2018 were analyzed concerning clinical characteristics at initial diagnosis, treatment and course of the disease.
resultsIn this study 45 patients with skull base metastases and cranial nerve deficits were included. The most frequent primary tumors were prostate cancer (27%), breast cancer (22%) and multiple myeloma (16%). The most involved cranial nerves were trigeminal nerve (42%), oculomomotor nerve (33%) and facial nerve (27%). Of the patients 84% had additional bone metastases outside the skull base. Dural infiltration or meningeal carcinomatosis were each observed in 13% of the patients. After radiotherapy cranial nerve deficits remained stable in 61% of all cases and in 22% symptoms improved. Median overall survival from treatment was 8 months (range 0.4-51 months). Patients with dose-escalated radiotherapy appeared to live longer (16.4 months vs. 4.7 months). This effect persisted in a multivariate analysis including the Karnofsky index, number of metastases, primary tumor and radiation dose (HR 0.37, p = 0.02).
conclusionSkull base metastases with cranial nerve deficits are complex diseases with poor prognosis. Precise diagnosis and treatment are required. Further research is needed to improve treatment.
