Is there a role for adjuvant radiotherapy after partial laryngectomy? A propensity score matched analysis.
Observational study in Acta otorhinolaryngologica Italica : organo ufficiale della Societa italiana di otorinolaringologia e chirurgia cervico-facciale, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To evaluate the impact of postoperative radiotherapy (PORT) on survival outcomes in patients with laryngeal cancer treated with partial laryngectomy. Methods: In this retrospective multicentre study, 312 patients with supraglottic or glottic squamous cell carcinoma treated with transoral laser microsurgery (TLM) or open partial horizontal laryngectomy (OPHL), with or without PORT between 2005 and 2022 were analysed. Propensity score modelling and inverse probability weighting were applied to balance baseline characteristics. Endpoints included disease-free survival (DFS), overall survival (OS), disease-specific survival (DSS), and locoregional control (LRC). Results: Of 312 patients, 175 underwent surgery alone and 137 received PORT. Treated patients had more adverse features. PORT significantly improved DFS (hazard ratio [HR] 0.44, 95% confidence interval [CI] 0.25-0.77) and LRC (HR 0.06, 95% CI 0.01-0.25). A significant benefit was also observed for DSS (HR 0.40, 95% CI 0.18-0.92). No statistically significant difference in OS emerged (HR 0.75, 95% CI 0.40-1.37). Conclusions: PORT significantly improves DFS and LRC after partial laryngectomy in high-risk patients, supporting its role in carefully selected cases.
