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
Introduction Patients with hepatocellular carcinoma (HCC) involving the inferior vena cava (IVC) and/or right atrium (RA) often experience debilitating symptoms, including lower extremity edema, dyspnea on exertion, shortness of breath at rest, chest pain, and ascites, that impact quality of life. The efficacy of external beam radiation therapy (EBRT) in palliating these symptoms is unclear. Thus, we sought to assess the effectiveness of EBRT in the palliation of symptoms and treatment outcomes in this patient population. Materials and methods All patients with HCC that compressed or invaded the IVC, received EBRT, and had a two-month follow-up visit to assess clinical response at our institution between 2010 and 2018 were analyzed. Patient demographics and clinical features were retrieved from the electronic medical record. Local control, local progression-free survival, and overall survival (OS) were measured from the last day of EBRT and calculated using the Kaplan-Meier method. Results Twenty-six patients with invasion or compression of the IVC were identified, 11 of whom (42%) had involvement of the RA. The median follow-up was 3.6 months. Five patients (19%) were treated with stereotactic body radiation therapy (SBRT) (all with five fractions) and 21 patients (81%) were treated with fractionated radiation therapy (range 10-16 fractions), both to a median dose of 3,000 cGy (range 2500-4000 cGy for SBRT, 2500-3750 cGy for fractionated radiation therapy). Significant proportions of patients experienced symptomatic relief from peripheral edema (54%), dyspnea on exertion (57%), shortness of breath (83%), chest pain (67%), and ascites (25%) after receiving EBRT. Additionally, they experienced few toxicities, with zero experiencing grade three or higher toxicities. One-year and two-year local control rates were 11.5% and 7.7%, respectively, and the median local progression-free survival was 4.8 months. One-year and two-year OS rates were 38.4% and 38.4%, respectively. Conclusions Our results suggest that EBRT should be considered as a potential treatment option for patients with HCC invading or compressing the IVC with or without involvement of the RA. EBRT was very well-tolerated and effectively palliated a variety of symptoms in patients with advanced disease.
