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

The presence of a fourth supernumerary molar in the mandible represents a rare anomaly of dentofacial development. Here, we describe an exceptional, previously unreported case of a 33-year-old man with a solitary ectopic supernumerary fourth molar located in the sigmoid notch, which was associated with a dentigerous cyst. In addition, a review of the literature related to this uncommon and atypical clinical presentation is provided. The patient presented with persistent pain and intermittent swelling on the ipsilateral side of his face. Previous radiographs revealed that, over a 10-year period, the fourth molar had migrated from a position distal to the third molar to the mandibular notch. Surgical extraction of the supernumerary tooth and enucleation of the associated cyst via an intraoral approach averted the cyst recurrence and other complications. This clinical report highlights the importance of early detection and surgical intervention to prevent cyst formation and the atypical migration of supernumerary teeth. It also emphasises the need for periodic follow-up to avoid associated complications.
