Correlation of immune makers with HPV 16 infections and the prognosis in oropharyngeal squamous cell carcinoma.
Article in Clinical oral investigations, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
objectivesThis study aims to investigate the association of immune markers with high risk human papillomavirus 16 (HPV 16) infection status and to evaluate the prognostic value of programmed death ligand-1 (PD-L1) in patients with oropharyngeal squamous cell carcinoma (OPSCC). MATERIALS AND
methodsThis retrospective study collected 50 cases of HPV positive and HPV negative OPSCC from January 2011 to December 2015. The correlation of CD8 + tumor infiltrating lymphocytes (TILs), programmed death-1 (PD-1), and PD-L1 expression with HPV 16 infection status was analyzed via immunofluorescent staining and quantitative real-time PCR.
resultsThere was no significant difference in the baseline data between the two groups. Patients with HPV + OPSCC had better prognosis compared to HPV - patients (5-year overall survival [OS], 66% vs. 40%, P = 0.003; 5-year disease specific survival [DSS], 73% vs. 44%, P = 0.001). The expressions of immunity related makers were significantly higher in the HPV + group than the HPV - group (CD8 + TIL: P = 0.039; PD-L1: P = 0.005; PD-1: P = 0.044). Positive CD8 + TIL and PD-L1 were independent factors for better prognosis of OPSCC (DSS, P < 0.001; OS, P < 0.001, respectively). Kaplan-Meier survival analysis indicated that patients with TILs of high HPV + /CD8 + expression were more likely to have better prognosis than those with TILs of low HPV + /CD8 + expression (DSS, P < 0.001; OS, P < 0.001), TILs of high expression of HPV - /CD8 + (DSS, P = 0.010; OS, P = 0.032), and TILs of low expression of HPV - /CD8 + (DSS, P < 0.001; OS, P < 0.001). Furthermore, HPV + /PD-L1 + OPSCC patients had significant better prognosis compared to patients with HPV + /PD-L1 - (DSS, P < 0.001; OS, P = 0.004), HPV - /PD-L1 + (DSS, P = 0.010; OS, P = 0.048) and HPV - /PD-L1 - (DSS, P < 0.001; OS, P < 0.001).
conclusionsHPV + OPSCC had a significantly better prognosis, and PD-L1 expression was elevated in HPV + OPSCC. PD-L1 positivity might be related to the better prognosis of HPV + OPSCC. CLINICAL RELEVANCE: This study provides a theoretical basis and baseline data for the application of immune checkpoint inhibitors in head and neck tumors.
