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
Background: There is an unmet clinical need for the locoregional recurrent head and neck squamous cell carcinoma (HNSCC). Moreover, little data regarding the therapeutic survival outcomes are available for the unresectable recurrent setting that did not receive radiotherapy during the initial course of treatment. Objectives: To investigate the survival outcomes of radiation-naïve recurrent HNSCC who were treated with first-line immunotherapy-based systemic therapy in combination with radical locoregional radiotherapy. Design: This is a retrospective study. Methods: From January 2019 to December 2023, locoregional recurrent HNSCC patients receiving immune checkpoint inhibitor (ICI)-based systemic therapy plus locoregional radiotherapy as first-line treatment in our institution were selected. Median follow-up was 16.4 months. Results: A total of 23 patients with recurrent HNSCC met the inclusion criteria and were finally analyzed. The median time to progression from the beginning of initial course of treatment was 9.3 months. Nineteen patients (82.6%) harbored recurrent stage IV (rIV) disease according to AJCC eighth edition, and 17 (73.9%) patients were assessed unresectable. For overall cohort, the median progression-free survival (PFS) and locoregional progression-free survival (LRPFS) were 17.0 months and 27.2 months, while the median overall survival (OS) and distant metastasis-free survival (DMFS) were not reached. The 1-year OS, PFS, LRPFS, and DMFS were 100%, 79.5%, 79.5%, and 100%, respectively. Twenty patients obtained objective response during the treatment course, achieving the 1-year duration of response (DOR) of 75.3%, and the median of 16.7 months. Combined positive score (CPS) ⩾ 20 was unveiled to be correlated with significantly favorable PFS compared with CPS < 20 or unknown (1-year PFS: 100% vs 50.0%, Conclusion: This study presented promising survival and tumor control with durable response in recurrent HNSCC, supporting the use of radical RT as the first-line treatment in addition to ICI-based systemic therapy, in particular for patients with CPS ⩾ 20.
