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
purposeA 15-gene hypoxia classifier has been developed and validated as a predictive factor for patients with head and neck squamous cell carcinoma treated with radiotherapy and nimorazole. This paper aimed to investigate the role of this hypoxia classifier as a prognostic factor for patients with oropharyngeal cancer (OPC) treated with accelerated chemoradiotherapy.
methodsP16 and 15-gene hypoxia classifier status, categorising tumours as more or less hypoxic, were determined for 136 OPC patients. Locoregional recurrence rate (LRR) and overall survival (OS) were estimated with cumulative incidence function and Kaplan-Meier method, respectively, stratified according to p16 and hypoxia status.
resultsP16-positive patients (34.6%) had significantly better LRR and OS than p16-negative patients. The 5‑year LRR of patients with more hypoxic OPC was similar to those with less hypoxic OPC in the overall patient population (27.3% versus 25.1%; p = 0.98; HR = 1.01 [CI95% 0.47;2.17]) and in the p16-negative OPC (36.4% versus 30.1%; p = 0.70; HR = 1.17 [CI95% 0.53;2.56]). No significant OS differences could be observed in neither p16-negative nor p16-positive subgroup with a 5-year OS for p16-negative more hypoxic OPC of 44.2% versus 49.0% in the less hypoxic OPC (p = 0.92; HR 0.97 [CI95% 0.51;1.84]).
conclusionNo significant outcome differences were observed between more or less hypoxic tumours, as determined by the 15-gene hypoxia classifier. These results suggest that the 15-gene hypoxia classifier may not have prognostic value in an OPC patient cohort treated with accelerated chemoradiotherapy.
