A case report of thyroid-like low-grade nasopharyngeal papillary adenocarcinoma with literature review.
Article in Frontiers in 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
Objective: This paper aims to systematically investigate the clinical and pathological characteristics of TL-LGNPPA and its differential diagnosis, with the objective of enhancing our understanding of this tumor and facilitating the development of more precise treatment strategies. Methods: A systematic review and meta-analysis of the clinical and pathological features, as well as differential diagnosis, of a case of TL-LGNPPA were conducted, and a comprehensive literature review was conducted by analyzing relevant articles published on PubMed. Results: The histological features of TL-LGNPPA are typically characterized by typical papillary and ductal structures, with fibrovascular axis present in the interstitium. Focal nuclear grooves may occasionally be seen, with moderate degree of atypia. Immunohistochemical analysis showed that all tumors expressed TTF-1 and CK, but TG was mostly negative, and the Ki-67 proliferation index was generally less than 10% in most cases. Conclusions: TL-LGNPPA is a rare nasopharyngeal tumor with histological features similar to papillary thyroid carcinoma. An accurate diagnosis requires a comprehensive consideration of histological morphological assessment, immunohistochemical analysis and imaging examination.
