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 an ectopic pleomorphic adenoma occurring in the glabellar region of an adult patient and perform the first known scoping review of the literature on ectopic pleomorphic adenomas of the head and neck, seeking to summarize their symptomatology, presentation, and treatment. Two independent reviewers performed searches and qualitative synthesis of relevant literature using PubMed, Embase, and Ovid All EBM Review databases. The authors adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review (PRISMA-ScR) statement. Included studies reported ectopic pleomorphic adenoma originating above the clavicle. Exclusion criteria included tumors as a result of metastasis or of non-salivary gland origin. Forty-six case series and case reports of ectopic pleomorphic adenomas met the inclusion and exclusion criteria, for a total of 48 tumors. Most cases occurred during the 2nd to 6th decades of life with a male:female ratio of 1:1.2. Ectopic pleomorphic adenomas typically presented as a slow-growing, firm, mobile mass on a superficial region of the head or neck. Pain was reported in 19% of cases. All cases were treated with surgical excision, and there was only one recurrence after a malignant transformation.
