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
Objective: This study aimed to investigate the effectiveness and safety of CyberKnife in the treatment of primary pancreatic cancer with metastases to the gastrointestinal tract (ie, primary pancreatic adenocarcinoma metastasizing to gastrointestinal organs). Methods: A total of 106 patients with primary pancreatic cancer and metastases to the gastrointestinal tract admitted to our hospital received CyberKnife treatment. Recent treatment efficacy (assessed at 3 months post-treatment), median survival period, pain levels, and adverse reactions were analyzed. Results: Among the 106 patients, 17 cases (16.04%) achieved complete response (CR), 61 cases (57.55%) achieved partial response (PR), 20 cases (18.87%) had stable disease (SD), and 8 cases (7.55%) had progressive disease (PD), resulting in an objective response rate (ORR) of 73.59% and an overall disease control rate (DCR) of 92.45% (98 cases). The one-year and two-year overall survival (OS) rates were 74.53% and 55.66%, respectively, while the local control (LC) rates were 92.45% and 87.74%, respectively. The median OS was 8.17 months (range: 1-25 months). Mean pain scores (Visual Analog Scale) decreased significantly from 5.38±1.37 at baseline to 2.01±0.35 post-treatment (p<0.001). Abdominal and lumbar pain significantly improved after 2 weeks of radiotherapy. Among the 68 patients with baseline pain who experienced relief, analgesic medication was discontinued in 25 (36.8%) patients, reduced by ≥50% in 18 patients (26.5%), and by approximately 25% in 5 patients (7.3%). Quality of life improved in 27 patients, remained stable in 52, and declined in 27, yielding an overall improvement or stabilization rate of 74.53% (79 cases). Conclusion: CyberKnife SBRT appears to be a promising treatment modality for managing primary pancreatic cancer with metastases to the gastrointestinal tract, with minimal adverse reactions.
