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
Systemic chemotherapy followed by whole brain radiotherapy (WBRT) is a widely used treatment strategy for patients with primary central nervous system lymphoma (PCNSL). However, the outcome of this treatment strategy in elderly patients, particularly with a poor prognostic score, was disappointing compared with younger patients, and the deterioration of cognitive function after WBRT is more problematic in these patients. To avoid this debilitating complication of WBRT and increase treatment efficacy in elderly patients, we designed systemic chemotherapy that incorporated interim gamma-knife surgery (GKS) treatment for elderly PCNSL patients (age≥65 years), omitting WBRT in this pilot trial. A total of four elderly patients with a poor prognostic score based on an International Extranodal Lymphoma Study Group were enrolled in this pilot clinical trial. All study patients acquired complete response and showed stable or improved neuropsychological function during the disease-free state. The median progression-free survival was 9.5 months (range 8.6-22.5 months), and the median overall survival was 15.8 months (range 13.3-25.1 months), which were likely to be similar to those of the chemotherapy followed by WBRT for those patients. This pilot study demonstrated that GKS-incorporated systemic chemotherapy can obtain complete response with high probability and considerably long survival, which suggests that this treatment strategy is efficient and neuropsychologically safe for elderly PCNSL patients with a poor prognostic score.
