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

Ranula is a benign salivary gland lesion originating from the sublingual salivary gland. This condition is primarily associated with salivary extravasation and retention due to obstruction or injury of the submandibular duct. A plunging ranula represents a rare variant occurring in the neck, submandibular, or submental regions, with bilateral presentations being particularly uncommon. Clinically, due to its lack of specificity, it is easily confused with other cervical lesions. This paper reports a case of a 25-year-old female presenting with bilateral painless submandibular masses. MRI revealed the characteristic bilateral "drooping tail sign". Following bilateral sublingual gland and cyst excision, the patient recovered well postoperatively with no immediate complications. At the two-month follow-up, no recurrence was observed, and symptoms were completely resolved. This paper aims to summarize the imaging features of bilateral plunging ranula and enhance clinical capacity for the differential diagnosis of this rare condition.
