1 · What the graph read from 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.

2 · The registry

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

Classification of neuroendocrine tumors in the paranasal sinuses is difficult, and the management of olfactory neuroblastoma with epithelial differentiation remains unclear. Recently, a group of tumors that exhibit neuroectodermal differentiation while maintaining distinct epithelial characteristics has been proposed as olfactory carcinoma, with reports indicating that these tumors have distinct clinical features and a worse prognosis than olfactory neuroblastoma. Here, we present a rare case in which an initial biopsy from the nasal cavity yielded a diagnosis of cylindrical cell papilloma, but surgical resection via combined transnasal endoscopic and transcranial approaches ultimately revealed a diagnosis of olfactory carcinoma. An accurate diagnosis is of the utmost importance for paranasal sinus tumors because it significantly impacts the treatment strategies and prognosis. In cases of olfactory carcinoma, sampling the glandular structure only may result in a misdiagnosis of papillary epithelial neoplasm. Therefore, sufficient tissue samples must be collected, and the entire tumor must be evaluated.
