Angina Bullosa Hemorrhagica of the Oral Mucosa: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Angina bullosa hemorrhagica (ABH) is a rare and benign condition characterized by the abrupt emergence of one or more blisters filled with blood inside the oral cavity. These blood-filled vesicles and bullae, which appear on the palate or oropharynx, are acute and occasionally painful. Its etiopathogenesis is unclear; however, it cannot be linked to systemic illnesses, vesiculobullous disorders, blood dyscrasias, or any other recognized cause. They were also identified in patients who use topical steroids or have diabetes mellitus or hypertension. Usually, the blisters burst within a day or two and heal on their own without causing any more pain or scars. The lesions are typically isolated and may cause patient anxiety due to a sudden onset. This case report's primary goal is to raise awareness to prevent misdiagnosis and improper treatment of the condition.
