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
Immunoglobulin G4-related disease (IgG4-RD) presenting with isolated nasopharyngeal involvement is rare. A 51-year-old man presented with left-sided otalgia and temporal tingling. Magnetic resonance imaging showed a 2.5-cm infiltrative soft tissue lesion in the left nasopharynx, initially suspected of being nasopharyngeal carcinoma. Serum IgG4 levels were normal. The first biopsy was inconclusive; however, a second, deeper biopsy confirmed IgG4-RD based on storiform fibrosis, dense lymphoplasmacytic infiltration, and increased IgG4-positive plasma cells. The patient responded well to moderate-dose glucocorticoids and azathioprine. IgG4-RD should be considered in the differential diagnosis of mass-forming lesions in the nasal cavity, even in the absence of elevated serum IgG4 levels.
