Interactions between hematological biomarkers of virus infection and immune cells in mediating distant metastasis in nasopharyngeal carcinoma: insights into prognosis and induction chemotherapy administration.
Article in Radiology and oncology, 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
backgroundConsidering the increased metastatic risk in hepatitis B surface antigen (HBsAg)-positive patients with nasopharyngeal carcinoma (NPC), we aimed to investigate the interactions among HBsAg, tumor burden indicators, and immune function in the accurate stratification of prognosis and treatment for this specific cohort. PATIENTS AND
methodsWe retrospectively analysed 1650 pathologically-confirmed patients with NPC from two centers and performed interaction and mediation analyses among HBsAg, plasma Epstein-Barr virus (EBV) DNA load, and absolute lymphocyte count (ALC), concerning distant metastasis. A 1:1 random matched-paired analysis was performed to evaluate survival according to risk and treatment stratification. Treatment-related adverse events were also compared.
resultsOverall, 17.3% (285/1650) of patients tested positive for HBsAg. Significant interactions occurred between HBsAg and low ALC (≤ 1.9×10
conclusionsInteractions exist between HBsAg positivity and high EBV/low ALC, mediating the effects of tumor staging and distant metastasis. The collective influence of viral infection, tumor burden, and reduced immune cells leads to worse DMFS in patients with HBsAg-positive NPC, requiring a tailored treatment beyond IC.
