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

Sebaceous neoplasms are a rare type of skin cancer that may occur in any area with sebaceous glands, including the outer third of the external auditory canal. However, documentation of the tumor originating in this location is limited to scarce case reports. In this location, malignancies can invade the temporal bone, typically requiring en bloc resection and radiation therapy. We describe a case managed with limited surgical excision based on criteria for primary squamous cell carcinoma of the external auditory canal with only close observation following surgery. Margins were free of disease following excision and histology demonstrated a favorable prognosis. The patient was disease free after a follow-up period of over 3 years postoperatively. A review of relevant literature is utilized to discuss clinical characteristics, staging, treatment, and prognosis to assist in clinical decision making for these patients.
