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
Apart from beam radiation (BR), treatment with radioactive implants (RI) was another important modality of cancer therapy. The main purpose was to explore which radiotherapy combined with chemotherapy was more beneficial and identify factor related to prognosis for patients with unresectable hepatocellular carcinoma (HCC). Patients were collected from the surveillance, epidemiology, and end results (SEER) database and were divided into RI group and BR group. Overall survival (OS) and HCC-specific survival were compared between two groups. Propensity score matched (PSM) was used to reduce baseline differences between the two groups. Univariate and multivariate Cox analysis were used to determine the factors affecting the prognosis, and a nomogram model was constructed based on independent risk factors. A total of 1481 HCC patients from 2000 to 2019 were enrolled, including 502 in RI group and 979 in BR group. After PSM, 376 pairs of matched cases were selected. In the matched cohort, there was no significant difference in the median OS (RI vs. BR, 15 vs. 17 months, P = 0.616) and HCC-specific survival (RI vs. BR, 18 vs. 21 months, P = 0.154) between the two groups. Subgroup analysis of different stages also showed no significant difference. Multivariate Cox analysis also did not indicate a significant prognostic difference between the two groups. Based on the independent risk factors of OS such as AFP, grade, TNM staging, and M1, a nomogram model was constructed and verified. When combined with chemotherapy in the treatment of unresectable HCC, RI demonstrated comparable prognostic outcomes to BR, suggesting its potential as an alternative treatment option. In addition, the constructed nomogram model might be able to intuitively and accurately predict the prognosis of unresectable HCC patients receiving chemotherapy combined with radiotherapy.
