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
Purpose: To evaluate the efficacy and safety of a multimodal therapeutic approach involving transarterial chemoembolization (TACE) in conjunction with helical iodine-125 (I-125) seed implant, lenvatinib, and programmed cell death-1(PD-1) inhibitors for hepatocellular carcinoma (HCC) complicated by main portal vein tumor thrombus (MPVTT). Material and methods: HCC patients with MPVTT treated with TACE coupled with helical I-125 implant, lenvatinib, PD-1 inhibitors between September 2019 and August 2022 were retrospectively analyzed, and constituted as study group. Those treated with TACE, helical I-125 seed implant, and sorafenib between December 2016 and August 2020 served as the historical control group. All patients received sorafenib or lenvatinib combined with PD-1 inhibitors within 3-7 days after TACE and helical I-125 seed implantation. The longest follow-up period for all patients in both groups was 36 months from the date of helical I-125 seed implantation. Primary outcome was overall survival time (OS), and secondary outcomes were progression free survival time (PFS), objective response rate (ORR), and disease control rate (DCR). The Cox proportional hazards regression model was employed to identify independent prognostic factors influencing OS and PFS. The value Results: A total of 53 patients were enrolled, with 22 assigned to the study group and 31 to the control group. The study group exhibited superior overall ORR(54.5% vs. 25.8%, Conclusions: The integration of the helical I-125 seed implant with TACE, lenvatinib, and PD-1 inhibitors is the safe and efficacious approach in the management of HCC complicated by MPVTT.
