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
backgroundMelanoma is one of the most common causes of brain metastases (BM). Despite recent therapeutic advances, survival in patients with brain metastases from melanoma (MBM) is dismal. In this study, we analyse the effect of concomitant treatment with stereotactic radiotherapy (SRT) and immunotherapy on survival, and of the location of BM on survival.
methodsAll patients with MBM diagnosed in Medisch Spectrum Twente, between 2011 and 2023 were included. Patient, radiological, and treatment variables were retrospectively collected. The primary outcome was overall survival (OS) and the secondary outcome was intracranial progression-free survival (IPFS). The effect of combination treatment (IRT), location, and other known prognostic factors on outcome measures was analysed using univariate and multivariate Cox regression. Location groups were divided into only supratentorial, only infratentorial, and both infra- and supratentorial BM.
results92 patients with MBM were included. The mean age was 64 years with standard deviation (SD) 12, median OS [interquartile range (IQR)] was 9.8 months [4.0-31.0] in the total population. No difference in OS was found between different treatment regimens (n = 56). Patients having both infra- and supratentorial BM showed a significantly reduced OS compared to having only supratentorial BM in multivariate analysis (Hazard Ratio (HR): 2.81; 95% Confidence Interval (CI):1.37-5.74; p < 0.01). IRT had a significantly positive effect on IPFS in univariate analysis (HR: 0.32; 95% CI: 0.13-0.77; p = 0.01).
conclusionConcomitant treatment of immunotherapy and SRT is associated with a prolonged IPFS compared to immunotherapy only. Having both infra- and supratentorial BM is an independent prognostic factor for a shorter OS.
