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
backgroundSystemic chemotherapy is the primary treatment strategy for recurrent or metastatic squamous cell carcinoma of the head and neck (RM-SCCHN). Therapeutic strategies are changing considerably with the introduction of molecular-targeted and immune checkpoint inhibitor (ICI) therapies in addition to conventional cytotoxic therapy. The CheckMate-141 and KEYNOTE-048 trials have enabled the use of ICIs as first-line treatment to improve the overall prognosis of RM-SCCHN. However, background factors affecting treatment responses, including performance status (PS), remain poorly defined. Therefore, we investigated the effect of PS in patients treated with nivolumab.
methodsWe retrospectively reviewed the treatment outcomes and backgrounds of 31 patients with RM-SCCHN who received nivolumab monotherapy between April 2017 and March 2023.
resultsThe patient background was male/female = 29/2, median age was 68 years (range 39-85), PS0/1/2 = 14/15/2, and oral/oropharynx/hypopharynx/larynx = 2/12/12/5. Median overall survival was 8.0 months (95% confidence interval [CI]: 4.3-30.6 months), median progression-free survival was 3.0 months (95% CI 1.7-9.1 months), and objective response rate was 22.6% (95% CI 11.1-40.1%). Immune-related adverse events of grade 3 or higher were observed in three patients (9.7%). Eight (29.6%) of the 27 patients (excluding four patients who maintained complete response for over 2 years) were successfully transferred to post-treatment. In the multivariate analysis, Eastern Cooperative Oncology Group (ECOG) PS (Hazard Ratio: 9.87, 95% CI 1.79-54.56) was associated with poor survival.
conclusionThe efficacy of nivolumab is reduced in patients with poor PS.
