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

We present a case of solitary neurofibroma in the masseter muscle that was excised via the high perimandibular approach (HPMA). A 52-year-old Japanese man complained of an uncomfortable feeling in his right buccal region. On examination, the buccal mucosa appeared normal, and overall, there were no skin disorders on the patient's body. Computed tomography revealed a well-defined 33 × 22-mm mass in the right masseter muscle showing a low density in the center and a slightly higher density at the margin of the mass. Magnetic resonance imaging also showed a hyperintense area on T1-weighted and T2-weighted images in the masseter muscle. An excisional biopsy was scheduled for the diagnosis of the intramasseteric mass. It was performed via the HPMA with the patient under general anesthesia. The final diagnosis was a neurofibroma. The patient recovered after the surgery without postoperative complications, including facial nerve damage and trismus. He was satisfied with the esthetic outcome, and the tumor has not recurred over a 24-month follow-up period. Altogether, these outcomes indicate that the HPMA is an effective and useful option for excision of a tumor in the masseter muscle.
