Evaluation of Anti-BNLF2b Antibody and Epstein-Barr Virus Biomarkers for the Diagnosis of Nasopharyngeal Carcinoma: A Retrospective Study.

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
ObjectiveTo validate the diagnostic performance of anti-BNLF2b antibody for detecting nasopharyngeal carcinoma (NPC) compared with healthy controls (HC).MethodsWe conducted a retrospective study including 220 patients with NPC, 61 with tongue cancer (TC), and 88 HC patients. We collected demographic and clinical data, including anti-BNLF2b antibody, EBV DNA, VCA-IgA, EBNA1-IgA, and Rta-IgG. Propensity score matching (PSM) was used to balance baseline characteristics between NPC and comparison groups. Associations between biomarkers and NPC diagnosis were examined using logistic regression. Diagnostic performance was evaluated using receiver operating characteristic (ROC) analysis.ResultsAfter PSM, 88 patients with NPC were matched to 88 HC with balanced baseline characteristics. Anti-BNLF2b antibody levels were significantly higher in NPC and remained independently associated with NPC diagnosis. For NPC versus HC, anti-BNLF2b antibody showed excellent discrimination (AUC = 0.990; sensitivity 98.9%; specificity 92.0% at a cut-off of 0.210), exceeding the performance of the EBV dual antibody risk probability (AUC: 0.872; P < 0.001). In addition, patients with NPC had higher anti-BNLF2b antibody levels and other EBV-related markers than those with TC.ConclusionIn this retrospective study, anti-BNLF2b antibody demonstrated excellent discrimination for NPC. It may serve as a complementary serologic marker, pending external validation and prospective assessment of clinically optimized cutoffs.
