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

backgroundTo systematically review the literature on clinicopathological features of keratoacanthomas (KA) in the oral and perioral region. MATERIAL AND

methodsThe review protocol as registered under the number CRD42022323274. Electronic searches were conducted in four databases with a specific search strategy using MeSH and free terms.

results60 studies reporting 73 cases of KA were included in this systematic review. KA affects more men with a mean age of 49.09 years old. Sun-exposed area of the lower lip was the most common anatomical location of the perioral lesions (38.35%) and the oral mucosa (9.58%) of the intra-oral ones. The most frequent clinical presentation of the perioral lesions was of an ulcerated nodule (36.23) and intra-orally of an papule (11.59) or nodule (11.59). Incisional biopsies were the commonest procedure for the diagnosis. The histological findings commonly presented a hyperplastic epithelial tissue forming a crater-like structure filled with keratin. Slightly atypia, keratin pearls and an inflammatory infiltrate in connective tissue could also be seen. Surgical excision was the treatment of choice in the majority of cases (45.71%). A low recurrence rate (6.89%) was seen in a mean follow-up time of 20.54 months.

conclusionsKA affects commonly sun-exposed areas of men in their sixth decade of life. Given the similarity of squamous cell carcinoma, it is important to study KA to help clinicians with the correct diagnosis and treatment.
