Nutritional characterization of patients with oropharyngeal cancers: impact of human papillomavirus status.
Article in European journal of clinical nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundOropharyngeal squamous cell carcinoma (OPSCC) of human papillomavirus (HPV)-positive status is increasing relative to HPV-negative disease. Nutritional features of OPSCC patients according to HPV status is unclear. SUBJECTS/
methodsCanadian and Spanish patients with OPSCC were assessed for body mass index (BMI), weight loss grade (WLG), and computed tomography-defined skeletal muscle index (SMI). Chi-square, t-test, Mann-Whitney-U, Kruskal-Wallis tests were conducted to compare HPV positive and negative groups. Overall survival (OS) was assessed by univariable Kaplan-Meier and Cox proportional hazard methods.
resultsNo differences in BMI, WLG, SMI, and adipose tissue index between the 308 (Canada) and 134 (Spain) patients according to HPV status; hence cohorts were pooled (n = 442). HPV-positive patients (n = 317) were overweight/obese (72.8%), had WLG of 0/1 (59.6%) and high SMI (83.4%) while HPV-negative patients were normal/underweight (61.5%), had high WLG 3/4 (50.8%), and moderate/severe SMI depletion (46.9%) (p < 0.003). These overall differences notwithstanding, there was crossover i.e. 35% of HPV-positive patients had high WLG and/or moderate/severe muscle depletion and 29% of HPV-negative patients had minimal weight loss and high SMI. HPV-negative patients had a higher risk of mortality (HR 3.78, 95% CI 2.70-5.29, P < 0.001) and this difference was retained after multivariable adjustment for WLG, SMI, age, disease stage, and planned treatment (HR 3.30, 95% CI 2.17-5.02, P < 0.001).
conclusionNutrition features of patients with OPSCC did not differ between Canada and Spain. Distinctive nutrition features exist in patients according to HPV status. The high heterogeneity of individual nutritional profiles invites an individualized approach to nutrition care.
