Impact of Timing the Combination of Radiotherapy and PD-1 Inhibitors on Outcomes in Patients with Hepatocellular Carcinoma.

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: The optimal timing for combining radiotherapy with immunotherapy in patients with hepatocellular carcinoma (HCC) remains uncertain and affects treatment efficacy and patient outcomes. This study aimed to evaluate and compare the efficacy and treatment-related adverse events (TRAEs) of synchronously administered radiotherapy and programmed cell death protein (PD)-1 inhibitors and sequential administration in patients with HCC. Patients and Methods: We retrospectively enrolled 67 patients with HCC who were undergoing liver radiotherapy and PD-1 inhibitor therapy at two medical centers between July 2017 and April 2023. Additionally, we created an experimental tumor model using 6-week-old female mice to validate our findings. Results: In the concurrent group, the median overall survival was indefinite; however, it was 13 months in the sequential group (95% confidence interval [CI] 6.7-19.3 months, Conclusion: Synchronous treatment demonstrated superior efficacy in treating HCC compared to sequential treatment, with manageable adverse events. The rapid increase in Tregs after radiotherapy may contribute to the reduced efficacy of sequential radiotherapy plus PD-1 inhibitors.
