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

Diffuse large B-cell lymphoma arising as a primary tumor in the frontal sinus is very rare. Moreover, it is often difficult to diagnose frontal sinus lesions. A 67-year-old Japanese man initially presented with diplopia and a swollen left upper eyelid. Diffusion-weighted magnetic resonance imaging suggested a malignant lymphoma of the frontal sinus, and subsequent extensive examination revealed diffuse large B-cell lymphoma of the frontal sinus with left orbital invasion. Six courses of combined immunodirected chemotherapy were administered. The patient is tumor-free owing to the accurate diagnosis of lymphoma at an early stage.
